Nitrogen is produced by utilising a combination of filtration and pressure swing adsorption (PSA) technology. Standard compressed air is filtered by high efficiency coalescing filters to remove all contaminants down to 0.1ppm. For ultra-sensitive applications such as GC -FID and GC -ECD, units also include the additional heated catalyst module to ensure hydrocarbons are removed to <0.1ppm. The air then passes through two columns filled with a carbon molecular sieve (CMS) which adsorbs O2, CO2 and moisture. These are desorbed to atmosphere during the pressure swing cycle leaving a supply of ultra-pure nitrogen.
