Principle of Operation
The Peak Scientific Hydrogen Generator uses a proton exchange membrane (PEM) that is extensively used in industrial and laboratory applications. The reliability of this type of membrane is assured as it was originally developed for NASA. To produce the highest purity of hydrogen that an analytical laboratory requires, Peak Scientific employs the services of a platinum catalyst in the electrode area. Electrolysis of water is the best method of producing high purity hydrogen on demand. 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 ion exchange membrane. When a continuous voltage is applied to the electrodes on the electrolyser cell, the following reactions take place: At the anode (the positively charged electrode), the water molecules loose two electrons forming an oxygen molecule and four hydrogen ions.
Anode 2 H2O - 4e = O2 + 4 H+
The oxygen that is produced in this half of the reaction is safely vented to atmosphere at the back of the generator. The four hydrogen ions that have been produced then pass through the ion exchange membrane (attracted by the negatively charged cathode) and collect four electrons reducing them to two hydrogen molecules.
Cathode 4 H+ + 4e = 2H2
The hydrogen produced is separated from the oxygen by the ion exchange membrane, which is impervious to molecular oxygen. Deionised water is the raw material 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 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 used - 1cc of water produces 1244cc of hydrogen. Some electrical energy is lost as heat, which is removed from the generator by the ventilation system. Hydrogen is generated on demand. By maintaining the user’s preset pressure and using this as a reference value, the generator will produce the exact amount of hydrogen required. As soon as the demand from the consuming application stops, then no gas is generated and the generator will maintain the supply lines at the preset pressure.

General Safety
The construction of the Precision 500 generator conforms to CEI / OSHA regulations as they do not store any appreciable amount of hydrogen internally. The generator only produces gas when the application places a demand on the unit. The unit also meets the European Electromagnetic Compatibility and Low Voltage Directives. The Generator is CE approved and has the CE mark attached. The maximum quantity of hydrogen stored in the generator at any one time is 400cc at a pressure of 6.9bar (100psi). This means that the Hydrogen Generator can be safely installed in your laboratory and does not classify the surrounding area as dangerous. All the Precision 500 hydrogen 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.

Generator Safety Features
The Precision 500 hydrogen generator has the following safety features to ensure safe and reliable operation: 1. To avoid any build up of hydrogen from leaks inside the unit; the generator features forced air ventilation. This ensures that a hydrogen / oxygen mixture cannot form inside the generator.
2. On power-up the generator self checks for internal leaks and if required it will shutdown at the end of the System Check informing the operator with a visual alarm. 3. The generator will detect any hydrogen leaks that occur within the generator, the user’s application and gas lines. In the event of a major leak the generator will automatically shutdown within 20 minutes. 4. The hydrogen pressure inside the generator should only reach a maximum of 7.5 bar (110psi) and this is controlled in two ways: a. Gas pressure is monitored and controlled electronically by a pressure sensor b. A mechanical pressure switch (Fail Safe) will electrically isolate the hydrogen cell should the internal pressure reach 7.5 bar (110psi) 5. When the generator is in alarm status the following occurs: a. The current to the cell is stopped so no hydrogen is generated therefore preventing a hazardous situation. b. The over pressure relief valve opens allowing the unit to depressurise. c. An audible and visual alarm relevant to the fault condition is displayed. The generator can sense for internal and external leaks, excessive gas demand and lack of water.

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 Swagelok® 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 1/8” OD for the H2 Exhaust and 3/8” OD for the H2Vent.

Start-up Sequence
CHECK: 1. Transport plugs have been removed
2. H2 Outlet is connected to application 3. Mains power is connected Turn the power switch ON. The digital display will light up, the cooling fans will rotate and the internal pumps may automatically run to load water if the internal tanks are not full. On power up the generator performs 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 next screen displayed to the user will be the Home screen, where two options will be 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 this screen are the Shutdown and Back options. Shutdown will depressurize the generator. This should be selected before turning the unit off using the Power switch at the rear of the unit. Finally, the Back option returns the user to the home screen where the Start option will allow the flow of hydrogen to the application. Upon selection the unit will take a few moments to adjust to the desired delivery pressure. 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 red 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 500. 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.

Supply Line Tubing
Peak scientific recommends using only clean grade copper or stainless steel for the supply tubing. The ring main and series lines should be ¼” OD with the Tpieces 1/8" on the incoming connections from the generators and 1/4" on the main line connections. The supply line for an expanded capacity system should be connected using t pieces as shown below, in the recommended ring main layout. This allows for the pressure to equalise.
To Instruments
Alternatively the system can be connected in a series as shown in the image below. If a series layout is chosen, the Master must be the unit closest to the instrument.
MASTER
To Instruments
Should any of the generators fail, hydrogen will continue to be supplied and the remaining units will increase supply to compensate. If the failed unit is the Master, the next machine in line will take over this role.

Unscrew the end cap of the Deioniser Column, this should be hand tight, and then remove the rubber O ring and sponge.
2. Pour the saturated resin out of the column and dispose of it. (See MSDS on P.30&31)
3. Remove the sponge from the bottom of the column.
4. Put a new sponge (05-3290) at the bottom of the column, then open the replacement gel pack (05-4110) and pour its contents into the column.
5. Fit a new sponge at the top of the column, refit the O ring and screw the lid back on the column, until the O ring is in contact with the cartridge. Ensure the lid is not over tightened, as this could damage the thread.
