On-Site Nitrogen Generator for Mass Spectrometry Lab — Genista BioSciences Case Study

The target

Genista BioSciences, an ISO-accredited food safety and quality testing laboratory in San Jose, California, needed a reliable on-site nitrogen supply for its mass spectrometry (LC-MS/MS) and gas chromatography (GC) instruments. The lab previously relied on delivered nitrogen cylinders, which created supply interruptions, rising gas costs, and safety concerns from handling high-pressure tanks. Genista required a continuous, oil-free, 99.5% purity nitrogen source to keep its analytical instruments running without downtime.

Solution

Safe Equip LLC installed a PSA (Pressure Swing Adsorption) nitrogen generator, model GN-30, rated at 19 SCFM with 99.5% nitrogen purity and 15–100 psig outlet pressure. The system includes an oil-free air compressor, refrigerated air dryer, multi-stage filtration, oxygen purity analyzer, and nitrogen/air buffer tanks — delivering a fully self-contained, low-maintenance nitrogen source for mass spectrometers and gas chromatographs. The system eliminates cylinder deliveries, reduces gas costs by generating nitrogen from ambient air, and is backed by a 5-year comprehensive service protection plan.
