HP Tower Nitrogen Generator

摘要

The HP Tower Nitrogen Generator 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 utilizing 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 0.1 ppm. 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 O_2, CO_2 and moisture. These are desorbed into the atmosphere during the pressure swing cycle leaving a supply of ultra pure nitrogen.
