Attention - Important Notice to All Users
WARNING
These instructions must be read thoroughly, section by section and
understood before installation and operation of your Peak Scientific
Hydrogen Generator. Please follow the appropriate safety standards for
handling hydrogen gas and other gases as determined by the laws and
regulations of your country.
Please save the product packaging for storage or future shipment of the generator.
1. For your own personal safety and to prevent accidental damage to your generator
please ensure that you read and understand our User Manual.
2. Do not store away the generator when not in operation. External water bottles must
be made of a dark coloured glass in order to prevent biological growth (available
from Peak Scientific). It is recommended that you check the water quality weekly to
prevent biological growth developing in the tank and tubing. Failure to do this will
greatly reduce the life of the generator and render the 3 year cell warranty void.
3. Do not place the external water bottle above the height of the generator. The bottle
may be placed at the same level or below the generator.
4. Use ASTM Type I or Type II water only. (1μS/cm or better). Failure to use the correct
quality water will invalidate the cell and system warranty. Do not attempt to connect
pressurised water to the generator.
5. It is recommended that you operate the generator at the lowest pressure permissible
for your particular application. Do not automatically set the pressure to maximum if
not required to avoid potentially damaging your application.
6. Failure to maintain the deioniser cartridge as recommended will reduce the
operational life of your generator and render its 3 year cell warranty void.
7. Do not attach any additional tanks or gas cylinders to your generator without first
consulting Peak Scientific.
8. Ensure your entire installation, both pipe work and analysers, are completely gas
tight. Even minor leaks will affect the operation of your generator and generally
reduce its operational life.
9. Has your generator been correctly sized for your application? If in doubt, consult
your dealer or Peak Scientific.

Principle of Operation
The Peak Scientific hydrogen generator produces high purity hydrogen gas, H2.
Hydrogen does not occur naturally on earth and must be formed via the decomposition
of other molecules, in this case via the splitting of water molecules into hydrogen and
oxygen in a process known as electrolysis.
The electrolyser used in the Peak Scientific hydrogen generator is known as a Proton
Exchange Membrane (PEM) electrolyser. This type of electrolyser was first described
in the mid-1960’s by General Electric as a method for producing oxygen for the Gemini
space program. PEM electrolysis has been continually developed since its introduction
and has remained the state-of-the-art technology for water electrolysis and the
production of high purity hydrogen ever since.
The most important element of the generator is the electrolyser cell where the
electrolysis reaction takes place. This consists of two electrodes (an anode and a
cathode), which are separated by the proton exchange membrane which gives the
technology its name. During operation deionised water is fed to the anode of the
electrolysis cell where it is split into oxygen, protons and electrons with the aid of a
precious metal catalyst. The oxygen is vented to atmosphere from the generator. The
protons travel across the membrane and simultaneously the electrons travel around the
external electrical circuit. These protons and electrons then recombine at the cathode of
the electrolyser, again with the aid of a precious metal catalyst to produce the hydrogen
gas. The high purity of the hydrogen is assured by the membrane which completely
separates the hydrogen produced at the cathode from the oxygen being produced at
the anode. These processes are described by the following equations:
Anode Reaction
H2O(l)
½O2(g) + 2H+(aq) + 2e-
Cathode Reaction
2H+(aq) + 2e- H2(g)
Deionised water is critical to the operation of the system and must have a purity of
1μS/cm or better to prevent damage to the membrane. Failure to use this grade of
deionised water will invalidate the 3 year cell warranty of your generator. The water is
automatically loaded (either at power up or periodically during operation) and the rate
at which the water is consumed depends on the amount of hydrogen being produced.
A small amount of the electrical energy input is lost as heat and this is removed from the
generator by the ventilation system.
The Peak Scientific hydrogen generator generates hydrogen on demand. By maintaining
the user’s pre-set pressure and using this as a reference value, the generator will
produce the precise amount of hydrogen required. As soon as the demand ceases, no
further hydrogen will be sent to the user’s application. During this time bubbles may still
be observed in the separating tank. This is due to the generator maintaining its internal
pressure and ensuring that clean, dry hydrogen is available immediately on demand
when the user requires it.
Page 20
General Safety
The generator produces gas when the application places a demand on the unit. The
maximum quantity of hydrogen stored in the generator at any one time is 300cc for
Precision Hydrogen and 350cc for Precision Hydrogen Trace, at a pressure of 6.9bar
(100psi). The unit also meets the European Electromagnetic Compatibility and Low
Voltage Directives. The Generator is CE approved and has the CE mark attached.
The Precision Hydrogen range has been tested according to EN60079-2 as part of Peak
Scientific’s risk assessment evidence provided as part of the CSA Accreditation process.
This means that the Hydrogen Generator can be safely installed in your laboratory and
does not classify the surrounding area as dangerous.
All of the Precision Hydrogen Series generators have the necessary control circuitry,
both electrical and mechanical, to ensure the shutdown of the instrument in the event of
a fault or faults occurring.
Page 21
Generator Safety Features
The Precision Hydrogen range have the following safety features to ensure safe and
reliable operation:
•
Overpressure sensor.
•
Safe and accurate control of pressure.
•
Capacity excess for leak detection.
•

Page 22
Unpacking
Although Peak Scientific takes every precaution with safe transit and packaging, it is
advisable to fully inspect the unit for any sign of transit damage.
Check ‘SHOCKWATCH’ and ‘TIP-N-TELL’ labels for signs of rough handling prior to
unpacking.
Any damage should be reported immediately to the carrier and Peak Scientific or the
Peak Partner from where the unit was purchased.
Follow the unpacking instructions posted on the side of the crate. It will require two

Unpacking Instructions
The generator weight constitutes a two person lift and as such, safe lifting practices
should be employed; do not attempt to lift on your own, as you will significantly increase
the chance of injury & damage to yourself and others around you.
1. Cut the plastic strapping and remove the cardboard lid, protective foam packaging
and cardboard sleeve. Finally remove the plastic covering the generator.
2. Next, with someone on either side of the unit, position your hands underneath the
unit ready to lift.
3. Ensuring your knees are bent and your back is straight, lift the unit to the desired
location.
Page 24
Transit Plug Removal
All hydrogen generators should be fitted with two Transit Plugs 3301437 during the
packaging process. These plugs are fitted to the H2 vent and O2 vent of all hydrogen
units and ensure no water from the internal water bottle can escape during transit.
Plugs should be removed during the installation of the generator.
These plugs require very little force to remove and will self-remove if left in the vents
3301437
Page 25
Installation
Location
The generator should be located on a flat, level surface for operation - this will ensure
that the water level sensors within the unit operate correctly. Some components in the
generator produce heat during operation and therefore an adequate airflow must be
maintained around the generator to allow the ventilation system to perform efficiently.
If the generator is stored in an enclosed space the environment must be controlled via
an air conditioner or extraction fan. The provision must be made to allow the volume
of air in the room to be changed 5 times per hour. The risk with hydrogen is a leak into
the environment raising the hydrogen content to the explosive limit. The rear of the
generator will become warm to the touch during operation - a minimum clearance of 15
cm (6”) from other bodies is recommended.
Do not obstruct or connect the vents to any application. Failing to observe this could
lead to permanent damage of the generator.
Do not expose the unit to freezing conditions. Please adhere to the operating
temperatures below:
Do not position the equipment so that it is difficult to disconnect the mains plug.
Minimum Operating Ambient Temperature:
10 °C (50 °F)
Maximum Operating Ambient Temperature:
35 °C (95 °F)
Note: It is recommended that any Precision Trace unit is left to run for 24 hours
before utilisation.

Tubing
For the hydrogen supply line, it is recommended that only clean grade copper or
stainless steel tubing should be used.
Plastic tubing material such as Teflon®, polyvinyl chloride, or Tygon® should not be used
when plumbing GCs since these materials will allow air and water to diffuse into the gas
lines. In addition, plastic tubing can give off organic impurities which can cause ghost
peaks and baseline instability.
Furthermore Peak Scientific recommend that compression fittings are used, and that the
fittings are free from Teflon® tape.
H2 Ventilation
Peak Scientific recommends that both the H2 Exhaust and H2 Vent ports at the rear
of the unit should be connected to an exhaust hood, or other ventilation system, to
ensure safe disposal of vented gasses. Tubing sizes for the vent ports are 6mm OD for
the H2 Exhaust and 6mm OD for the H2 Vent. If the 1m length of PTFE tubing (00-4411)
supplied in the generator fittings kit is insufficient to reach the nearest fume hood or
ventilation system, we would recommend using tubing of sufficient length, which can
be ordered from Peak Scientific. Please do not attach the 1m length of supplied tubing
(00-4411) to the H2 Exhaust or H2 Vent ports if NOT venting gas away to a fume hood
or ventilation system as this can result in a localized build-up of hydrogen gas.
Page 29
Water Quality
Use only High Grade Deionised water, which must have a conductivity of less than or
equal to 1μS/cm @ 20°C and should be replaced as required. Water quality should be
checked prior to being used to supply the Precision Hydrogen (Trace) Generator.
Use of water in the Precision Hydrogen (Trace) Generator with a purity not specified
above will result in a reduced efficiency of hydrogen production, failure of the generator
and loss of warranty.
Water should be stored in a UV protected dark container away from direct sunlight. The
bottle should have a vented lid to minimise any dust or debris contaminating the water
supply. A suitable external water bottle is available from Peak Scientific.
Note: Customers should check the water quality of the external water supply once a
week to maintain the health of the generator.
Automatic Filling
The Precision Hydrogen generator uses an automatic water filling system, whereby
sensors in the unit’s internal water tank detect when the water level reaches a minimum.
This then refills the tank using a rear connection to an external DI water supply.
The unit should be connected to the water supply as shown on the next page.
Using the length of Tygon tubing and the hose barb fitting from the fittings kit, attach
the barb to the tubing. Then connect one end to the water supply and the other to the
Fill port at the rear of the Precision Hydrogen.
For efficient water filling the external supply should be no more than 2 metres away
from the connection on the generator.
The DI Water Supply source MUST NOT be located higher than
the height of the surface that the Precision Hydrogen generator is
placed upon. A supply located higher than specified will result in the
generator’s internal water bottle over filling.
WARNING
A pressurized DI Water Supply Source will also result in the internal
water bottle over filling, and also MUST NOT be used.

Menu
The external water supply should be checked prior to pushing the Confirm button which
will then re-engage the load pump and will allow the generator to continue to fill with
water. If the generator again fails to load water the below screen will be displayed.
Water Level Fault
A problem with the water
sensors has been detected.
Start
Page 31
Menu
When the system detects a low water level it starts a 3 hour timer, should the system not
receive enough water to switch the low level sensor it will then stop the generator from
producing hydrogen. This happens to prevent damage to the hydrogen cell and ensure
that your Precision Hydrogen Generator remains in its optimum operating condition.
If the generator has reached this point the screen below will be shown on the Human
Machine Interface (HMI).
Water Level Fault
There is no water in the generator.
The generator has been shut down to
prevent damage to the cell.
Start
Menu
To resolve this, check your external supply before cycling the power on the generator.
Once the low level water sensor disengages the generator will then begin producing
hydrogen as before.
Four and eight litre water storage bottles can be purchased from Peak Scientific, please
contact your Sales Representative for more information.
Page 32
Draining the Water Tank
1. Before draining the generator, ensure that you have tubing with a barbed connector
and a vessel to collect drained water
2. Connect tubing to the ‘Drain’ port on the rear of the Precision Hydrogen generator
using the barbed fitting with loose end in the vessel
3. Once the barbed fitting is inserted into the drain connector, water will drain from the
generator’s internal tank into the vessel
4. Fill the external water bottle with fresh DI water (ASTM type II)
5. Once the internal tank of the generator is emptied, connect the barbed connector to
the ‘Fill’ port of the generator and the generator will automatically draw water from
the external water bottle

Start-up Sequence
CHECK:
1.
H2 Outlet is connected to application
2.
Mains power is connected
Turn the power switch ON. The digital display will light up, the cooling fan will rotate.
On power up the generator will check the water level, once the water level is at the
minimum level required the generator will perform a diagnostic check including a leak
test, this should take approximately six minutes.
Upon successful completion of the leak test, the operator is presented with the main
screen and the generator is ready to deliver hydrogen.
The main screen has two options available, Start and Menu. The first time the unit is
switched on the user should select the Menu option which allows the desired unit of
measure and delivery pressure to be selected.
Also displayed on the Menu screen are the Shutdown and Back buttons. Shutdown will
depressurize the generator. This should be selected before turning the unit off using
the Power switch at the rear of the unit. The Back button returns the user to the home
screen where the Start option will allow the flow of hydrogen to the application.
If the unit has been used previously the Start button will initiate the supply of hydrogen
to the application at the last used pressure.
Note: If leak test is unsuccessful, and alarm will sound and a Yellow failure screen will be
displayed complete with a mute button. The user is prompted at this point to contact
their Peak service provider.
Liquid Leak Detectors
Liquid leak detectors should not be used on the Precision Hydrogen. These solutions
are easily drawn into the high purity hydrogen gas system and can cause irreparable
damage to a GC column. If a liquid solution has to be used, then it should be IPA based,
or a portable hydrogen detector should be used.
Gas Traps
It is recommended that moisture, oxygen and hydrocarbon traps are used on the
gas supply line between the Peak generator and the instrument to provide back-up
contaminant protection for your instrument.
The hydrogen gas produced by the Precision Hydrogen will be sufficiently pure for these
contaminant traps to last a long time, but should a leak ever occur on the gas line, the
traps will ensure that any harmful contaminants are caught, thereby preventing potential
damage to the instrument.
Page 36
Expanding Capacity
CAUTION
These are not standard serial ports, damage to serial equipment is
highly likely if connected. 24Vdc signal level exists on certain pins with
a maximum power rating of 5W.
The Precision Hydrogen has an expandable feature, where the flow capacity of the unit
is increased, by connecting up to 16 units in a Master-Slave format.
Rear Connections
In order to use this feature the units must be connected together via the ‘Master’ port
on the first Precision Hydrogen, and the ‘Slave’ port at the rear of the next Precision
Hydrogen unit.
The first Precision Hydrogen unit is automatically defined as the Master, and before the
connections are made and H2 is supplied, the desired pressure must be set on all units.
This must be the same pressure for all.
The user can now press Start on the Master unit to begin the flow of H2. The Master will
now manage all the other units.
The Data Cables (08-8902) used to connect units together can be purchased from Peak
Scientific.

Press the Stop button on the Home screen, then press Menu and select Shut Down.
The unit will take a few moments to depressurize after which the power switch at the
rear of the generator can be switched off.
Cleaning
Clean the outside of the Generator, with the exception of the HMI screen, using only
warm soapy water and a clean damp cloth. Ensure the cloth is thoroughly rung out to
remove excess fluid prior to use.
Cleaning should only be undertaken with the power switched off and
the power cord removed from the rear of the Generator.
CAUTION
Under no circumstances should any solvents or abrasive cleaning
solutions be used as these can contain fumes that could be harmful to
the Generator.
To clean the HMI Screen, moisten a cloth with either isopropyl or ethyl alcohol.
CAUTION

Regeneration of Desiccant
When reactivating the desiccant it is vital that the activity indicator is not used to
control the process.
1. As a general rule saturated desiccant will require a minimum of 4-6 hours at a
temperature of between 105-110°C throughout the entire desiccant bed for the
reactivation process to be effective and reduce the adsorbed moisture to less than
2% by weight.
2. Reactivation should be carried out in a ventilated electric oven. A sealed oven
will limit the moisture liberated and prevent efficient reactivation. Gas ovens and
microwave cookers are also not suitable for reactivation.
3. Devices that pass warm air through the desiccant bed changing the activity indicator
to blue should be avoided.
4. Ideally after reactivation the desiccant must be placed in a sealed container and
allowed to cool. The reactivated desiccant should not be stored in a warm oven
at 60°C as this will cause partial saturation of the desiccant although the activity
indicator will remain stable.
5. To validate the reactivation efficiency a fundamental weight loss test conducted
before and after processing will provide the amount of moisture loss data.
6. A supply of pre-heated air is an integral requirement for an efficient reactivation
process. For saturated desiccant a minimum air flow of between 5-10 cubic feet per
minute.
