Nitrogen
generators are used in labs all over the world to supply numerous analytical
instruments with a reliable nitrogen gas source. Nitrogen Generator systems are still the efficient way to supply
instrument gas, unlike gas cylinders a nitrogen generator never runs out of gas
and continually supplies a reliable high purity of the gas. Nitrogen is an
inert gas meaning it is not reactive with other elements & chemicals.
Nitrogen is extremely abundant than any other element. Nitrogen gas is used in
lab analysis for decades. In the past, labs were mandatory to have their
nitrogen gas supply brought in cylinders or in bottles from their close nitrogen
plant, which for some labs could take numerous days to deliver. These cylinders
and bottles would then supply a Liquid Chromatograph Mass Spectrometer, or a
detector in the case of a Gas Chromatograph, letting the lab carry out its
analysis.
Uses of Nitrogen
generators in the lab
Nitrogen
Generator not only removes
the hassle of having to alter over cylinders, but it also provides a continuous
supply of gas at a reliable purity. This constancy is generated using one of 2 technologies,
Pressure Swing Adsorption and membrane nitrogen generators.
Membrane
nitrogen generator
The opinion of
operation for a membrane nitrogen generator is where atmospheric air is crushed
by an air compressor and accepted through a hollow fibre membrane, sifting out
parts of air and leaving behind a high purity nitrogen gas. More progressive
nitrogen generation systems can include numerous stages of filtration before reaching
the membrane, this eliminates more particles in the gas such as dust & moisture.
Fine mesh filters are used in the nitrogen generation process, as these are for
removing particles in the air while air dryers are used to eliminate moisture.
Beyond safeguarding the high purity of nitrogen, these additional filtration
stages will also guard the membrane.
