Page 19: Introduction
Introduction Precision Hydrogen SL has been developed to provide a source of high purity hydrogen gas, suitable for GC detector gas supply. Features include: • Easy to use single button interface • Status indicative lighting feature • Purities of up to 99.9995% Precision Hydrogen SL is based on proven technology, producing hydrogen by electrolysis using a Proton Exchange Membrane (PEM) cell. -
Page 20: Principle Of Operation
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... -
Page 21: 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. Any damage should be reported immediately to the carrier and Peak Scientific or the Peak Partner from where the unit was purchased. -
Page 22: Fittings Kit Contents
Fittings Kit Contents Supplied in the Fittings Kit are all the fittings required to connect the generator to the application. The contents of the Fittings Kit are as follows: 1. Tygon Tubing* x 1m 2. Barbed Hose Fitting* 3. In-line Water Filter** 4. -
Page 23: Installation
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. -
Page 24: Generator Overview
Generator Overview General Dimensions 160 mm / 6.3” 385 mm / 15.2” The Generator must always be placed on a flat, level surface. Failure to do so will affect the performance of the Generator. WARNING Page 24... -

Page 26: Tubing
Teflon® tape. H2 Ventilation Peak Scientific recommends that the H2 Exhaust port 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 port are 6mm OD. -
Page 27: Manual Water Tank Filling
Manual Water Tank Filling The generator must be filled with DI water to be functional. For manual fill systems, follow the below steps. 1. Lift the hinged lid back, then remove the tank cover. 2. Fill the water tank from your lab’s supply of DI water, and ensure the tank cover is replaced, afterwards. -
Page 28: Automatic Filling (Automatic Fill Upgrade Units Only)
Automatic Filling (Automatic Fill Upgrade units only) The Precision Hydrogen generator uses an automatic water filling system as an optional upgrade, 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 below. -
Page 29: Pressurized Filling (Automatic Fill Upgrade Units Only)
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. Pressurized Filling (Automatic Fill Upgrade units only) A pressurized feed option is available as a valve fitted to the fill inlet, instead of the load pump and can be supplied by 1-3 bar pressurized water feed. -
Page 30: Water Usage
Water Usage The water consumption rate of the Precision Hydrogen Generator is completely dependent on the rate at which the hydrogen is produced. The graphs below show an estimation of the water consumption from the generator in Stand-by mode through to maximum Hydrogen output. Page 30... -
Page 31: Electrical Connection
Electrical Connection Connect the generator into an appropriate electricity supply, between 100-240VAC. Refer to the generator serial plate for input specification and ensure your supply matches the requirements. If the appropriate power cord is not supplied; a new CSA, UL approved power cord, rated to at least 10 amps, can be fitted by a qualified electrician. -
Page 32: Start-Up Sequence
Start-up Sequence CHECK: Outlet is connected to application Mains power is connected Turn the power switch ON. The water tank will light up, the cooling fan will rotate and the generator will exhaust any stored hydrogen. 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 and during this time the tank illumination will cycle from dim to bright... -
Page 33: Switching The Unit Off
Switching the Unit Off The unit can be switched off at any time using the following procedure. The generator may be restored to a depressurized state by pressing and holding the front button for at least three seconds. This will cause the generator to cease hydrogen production, illuminate the water tank blue, and exhaust any stored hydrogen through the exhaust port at the rear of the generator. -
Page 34: De-Ionizer Cartridge Replacement
De-ionizer cartridge Replacement DI cartridge requires an annual change, although it should also be changed if the water supply is contaminated with water of a conductivity above the specified limit. Replacement of the DI column (the column in the middle of the water tank) is by rotating 90°... -
Page 35: Replacement Of Desiccant Capsule
Replacement of Desiccant Capsule The desiccant capsule has a minimum expected life of 12 weeks. The capsule consists of molecular sieve interspersed with silica gel, viewable through the window on the side of the generator. The capsule should be replaced when all of the silica gel has visibly darkened. - Page 36 3. The cap can then be replaced again using the dryer cap removal tool, ensuring not to over-tighten the cap and the hinged lid can be closed. 4. The unit can now be switched on. Page 36...
