How to use this Manual
This manual is intended for end users and has been written as a reference document
where you can skip to the relevant information.
Users can refer to the contents page to find the relevant information.
Please review each of the following sections carefully.
Thank you for selecting Peak Scientific to meet your gas generation needs, and should
you require any further assistance or support please do not hesitate to contact Peak
Scientific or the Peak Partner from which you purchased your generator.

Introduction
Precision is a modular system with differing flow rates that allows you to add multiple
generators as your gas and analysis demands change. The Precision Series will keep
your gas flowing with consummate accuracy and reliability, whatever your needs, while
fitting neatly into any lab space.
The Precision Nitrogen, Headspace and Nitrogen Trace Generators provide a constant
and consistent source of Nitrogen for detector make-up gas for GC applications, as
well as headspace vial pressurization, purge and trap, tube conditioning for thermal
desorption and sample blow down. In addition to these applications, the Precision
Nitrogen Trace model can be used for carrier gas in GC applications as it also removes
hydrocarbons by means of catalytic oxidation.
Other features include:
•

Generates Nitrogen on demand from compressed air.

•

Regenerative PSA Carbon Molecular Sieve to ensure Oxygen and Moisture removal.

•

Minimum maintenance with only a filter change per annum.

•

Small and Stackable.

With the Precision Nitrogen based on proven technology, it removes moisture and
oxygen to leave Ultra High Purity Nitrogen. The Nitrogen Trace further removes
Hydrocarbons (as Methane) to <0.05ppm.
To ensure these generator models meet our high expectations with regards to reliability
and performance, we have tested them extensively at our manufacturing plant and with
end users around the world to ensure reliability and longevity of the system.

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
people to remove the unit from the shipping crate and to manoeuvre the generator
onto the bench.
Please save the product packaging for storage or future shipment of the generator.
Note: Included with the generator is a “Fittings Kit” containing mains power leads for
UK, EU & US and also all the required fittings and warranty registration card. Be careful
not to discard these with the packaging.

Unpacking Instructions
The unit 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. Remove the screws encircled in red around the bottom of the crate lid and lift
upwards.
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 14

Installation
Generator Environment
The generator is designed for indoor use only. Storing of corrosive substances near
the generator or compressed air supply is not recommended. Saline salt solution
spillages around the generator or their compressed air supply should be cleaned up
immediately. It should be installed adjacent to the application(s) it is supplying. If this
is not convenient then the unit can be sited elsewhere, however, consideration should
be made of the lengths of pipe runs as pressure drops can result from extended runs of
pipe.
Performance of the generator (like all sophisticated equipment) is affected by ambient
conditions. Note should also be taken to the proximity of Air Conditioning outlets.
These can sometimes give rise to “pockets” of air with high relative humidity. Operation
of the unit within such a pocket could adversely affect its performance. Consideration
should also be given to the air flow around the unit. It is recommended that an air gap
of 75mm (3”) should be maintained down both sides and at the rear of the unit. Please
refer to the drawing below for the general dimensions of the unit.
Minimum Operating Ambient Temperature:

5 °C (41 °F)

Maximum Operating Ambient Temperature:

35 °C (95 °F)

Electrical requirements are 110 or 230VAC nominal +/- 10% depending on chosen
model. However, running continuously at voltages outwith this is not recommended.
Extended periods at extremes can have a detrimental effect on the operation and life of
the generator.
If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment maybe impaired.
WARNING

Page 20

Air Purity
The Precision Nitogen Series generator should be connected to an air supply that, as a
minimum, meets ISO8753-1:2010 Class 1.4.1

Class 1 Particulate
In each cubic metre of compressed air, the particulate count should not exceed 20,000
particles in the 0.1 - 0.5 micron size range, 400 particles in the 0.5 - 1 micron range and
10 particles in the 1 - 5 micron size range.

Class 4 Water
A pressure dew point (PDP) of +3°C or better is required and no liquid water is allowed.

Class 1 Oil
In each cubic metre of compressed air, not more than 0.01mg of oil is allowed. This is a
total level for liquid oil, oil aerosol and oil vapour.

Page 21

Start-Up Sequence
Switch the generator on using the power switch on the rear panel of the unit. Please
note: Air will only flow through the generator when the power is switched on. The LED’s
on the front panel will illuminate YELLOW for the start-up period.

YELLOW for 90 Minutes

The generator will purge impurities from its internal storage tank until Oxygen content
is less than 5PPM, approximately 1.5 hours (3-3.5 hours for Headspace) of uninterrupted
operation. On completion, the Fascia will illuminate GREEN or BLUE (70-**** Part
Numbers Only) and the generator is now ready to be connected to the application.

GREEN / BLUE



On Demand Gas
The generator will produce nitrogen on demand. If the application is operating
and requires a gas flow, the system it is connected to will supply this to suit the
requirements of the application. If the application requirement for gas stops, the system
will also stop, once it has reached its upper set limit in the internal storage tanks. If the
demand from the application starts again, the system will detect the demand for gas
and will automatically start again to suit the demand.

Unusual Operation
If at any time the generator begins to emit excessive noise or vibration, then it should
be switched off and you should contact Peak Scientific or the Peak Partner from which
the generator has been purchased.
Page 22

Connecting to the application
Once the initial purge run of 1.5 hours (3-3.5 hours for Headspace) has completed the
generator is now ready to be connected to the application(s).
The pressure in the internal storage tanks must be allowed to dissipate
before connecting the generator to the application(s)
CAUTION

Attach the ¼” compression fitting to the outlet of the generator. Using the ¼” tubing
supplied, connect the outlet of the generator to the inlet on the application.
If you require more tubing than is supplied please refer to the Tubing Lengths section.

CAUTION

Once the tubing is connected to the application, please ensure that it
is thoroughly checked for being leak-tight. Even the slightest leak in
the gas supply between the generator and the application can lead to
a reduction in efficiency.

Tubing Lengths

CAUTION

The diameter of the tubing which will be connected to the gas outlet is
important and is determined by the length of tubing required. Failure
to follow these recommendations could lead to an excessive pressure
drop between the generator and its application.

< 10 meters:

Use ¼”/3⁄16” (¼” O/D, 3⁄16” I/D) P.T.F.E. tubing.

> 10 - 40 meters: Use 3⁄8”/ 5⁄16” (3⁄8” O/D, 5⁄16” I/D). Tubing and fittings not supplied
in the fittings kit.
> 40 metres:


Please contact Peak Scientific with the relevant distance and
we will calculate the flow resistance and the tubing size required.

A combination of ¼”/3⁄16” and 3⁄8”/5⁄16” tubing may be used to ensure that there is no
large diameter tubing within the lab (i.e. for the first 20 meters from the generator
use 3⁄8”/5⁄16” and the final 10 meters to the application use ¼”/3⁄16” tubing). Keep the
connections and bends to a minimum.
