In today’s modern analytical laboratory compressed air is required for a wide range of different uses.
Different gases have always been important remedies in analytical laboratories and are the foundations of numerous analyses. Traditionally, gasses have been supplied in cylinders and distributed through a piped network. As consumption of gasses has increased so has the use of gas generators, since the traditional supply of gasses in cylinders is considered a rather uneconomic solution. Gas generators can produce the required gasses at the exact required flow and purity.
Several types of gas generators are available:
By removing hydrocarbons from the compressed air, this type of generator provides high purity zero grade air, used for gas chromatography (GC).
The FT-IR (Fourier Transform-Infrared Spectrometry) generator supplies dry, CO2 free air and gas to FT-IR spectrometers. Other generators for spectroscopy include NMR (Nuclear magnetic Resonance), ICP (Inductively Coupled Plasma) and AA (Atomic Adsorption)
The TOC (Total Organic Carbon) gas generator produces hydrocarbon- and CO2 free air used as carrier/combustion gas for TOC analyzers.
The utilization of the separation technique LC/MS has been increased dramatically and so has the demand for nitrogen and thus nitrogen generators. LC/MS is used as an analytical separation technique to identify components and clarify structures and chemical properties of molecules. The technique can identify human DNA, detect steroids in athletes and analyze medical drugs. The separation of the molecules is only possible with a constant flow of nitrogen at high purity and at the right pressure.
