New nitrogen generator eliminates need for long gas lines

Sep 06 2019 Read 275 Times

The HP Tower Nitrogen Generator, from VICI DBS produces a 24/7 on-demand supply of high purity nitrogen with a flow rate from 500 to 4,000 m/min, Purity up to 99.999% & <0.1ppm, and THC Pressure up to 5 bar.                 

The HP Tower Nitrogen Generator can be installed in the lab close to the instrument, thus eliminating the need for long gas lines from external cylinder supplies.         

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 into the atmosphere during the pressure swing cycle leaving a supply of ultra pure nitrogen.
