Laboratory
In today’s modern
analytical laboratory compressed air is required for a wide range of
different uses.

Gas
generation
|
|
|
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:
|
Zero-Air generator
|
|
By
removing hydrocarbons from the compressed air, this type of generator provides
high purity zero grade air, used for gas chromatography (GC).
|
|
FT-IR
Generator
|
|
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)
|
|
TOC
Generator
|
|
The
TOC (Total Organic Carbon) gas generator produces hydrocarbon- and CO2 free
air used as carrier/combustion gas for TOC analyzers.
|
|
Nitrogen generator
|
|
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.
