LAB Nitrogen Generator

Nitrogen as an inert gas is a very valued lab gas and is used for a number of lab applications.

Nitrogen finds it’s application in labs in Auto samplers, GC’s, LC/MS, Spectrometer, Nuclear Magnetic resonance (NMR), Protein analyzer, Solvent evaporators, Thermal galvanic Analyzer(TGA), Total Organic Carbon Analyzer etc.

Nitrogen is widely used in Gas chromatography because Most gas chromatography column stationary phases are based on modified polysiloxane or polyethylene glycol materials. These materials oxidize in the presence of oxygen at elevated temperatures. This behavior, known in part as bleed, will very quickly degrade the performance of the column.

LC-MS uses a HPLC system but at the point of the liquid mobile phases leaving the column the liquid sample is sprayed to produce micro-droplets. These evaporate rapidly releasing ionized analyte molecules which can then be separated in the MS. Large flow sprays can benefit from additional atomization or nebulisation using a high flow of Nitrogen.
