Various lab devices such as gas chromatograph-mass spectrometers (GC-MS), gas analyzers, electron microscopes, ion mobility spectrometers, and so on, require a consistent and reliable supply of clean, dry gas for optimal performance. Traditionally, high pressure gas cylinders have been utilized for the supply of carrier gases such as hydrogen, helium, and nitrogen for laboratories.
Helium is widely used for GC experiments, while hydrogen and nitrogen are now being sought as equal, if not better, and more sustainable alternatives. Hydrogen’s high diffusivity results in greater linear velocities and shorter analyses while nitrogen provides the best possible separation efficiencies at the lowest velocities.
In this article, you'll learn about:
- Making your lab safer through use of a well-maintained gas generator
- Reducing catastrophic equipment failure
- Preventing major repairs
- Extending system and component life
- Operating more efficiently
- Lowering unnecessary repair costs
- Reducing downtime
- Forecasting upkeep costs

Various lab devices such as gas chromatograph- mass spectrometers (GC-MS), gas analyzers, electron microscopes, ion mobility spectrometers, and so on, require a consistent and reliable supply of clean, dry gas for optimal performance.

GAS GENERATORS – A SAFER ALTERNATIVE
The biggest issue concerning carrier gases involves lab safety. Safety hazards associated with the handling
and storage of gas cylinders remain a persistent issue. Gas generators match these conditions to a tee and can provide carrier gases at various pressures, flow rates, and operating temperatures.
Unlike pressurized cylinders or tanks, gas generators provide an uninterrupted supply of gas and do not require replacement once empty. Rather than storing hydrogen under pressure in a tank, a hydrogen gas gen- erator would hold very little gas and make the carrier gas on an as needed basis. As such, gas generators are a much safer alternative.
MAINTAINING GAS GENERATORS
Preventative maintenance of gas generators can go a long way in helping prolong their lifespan. There are various reasons why regular maintenance of gas generator equipment is important:
Reduce the probability of catastrophic equipment failure
Prevent major repairs by catching issues early
Extend system and component life

Ensure maximum operational efficiency of equipment
Prevent unnecessary costs and unscheduled repairs
Assist in identifying parts that require replacement before a breakdown occurs
Reduce equipment downtime and sample run interruptions
Forecast equipment upkeep costs
With nitrogen generators, it is generally recommend- ed against operating the generator above an ambient temperature of 75°F or relative humidity of 75%.
Operation above these limits will drastically reduce the lifespan of the generator’s nitrogen membrane. Maintaining an 18’’ gap around the generator ensures optimum airflow, with routine maintenance being a must every 12 months or 4000 - 8000 hours, alongside use of the correct supply voltage.
For a hydrogen generator, it is advisable to use only high grade deionised water of 1μS/cm or better, and to replace the deioniser resin bags or columns every six months. Checking the condition of the desiccant regularly, where used, is also important. Upon 80% saturation, the desiccant must be changed. GGS pro- vides resin, desiccant, and advice to help maintain your hydrogen generator at optimum performance. Control- ling the water quality of the hydrogen generator is crucial and will ensure that the life of the hydrogen cell is maximized.
