Peak Scientific is a Scottish manufacturer of gas generators for analytical laboratories. [ 1 ] [ 2 ] [ 3 ] Headquartered in Glasgow , United Kingdom, it specialises in the production of nitrogen, hydrogen, and gas generators, mainly for the fields of liquid chromatography–mass spectrometry and gas chromatography .
With this variant of PSA developed for use in laboratory nitrogen generators, nitrogen gas is produced into two steps: in the first step, the compressed air is forced to pass through a carbon molecular sieve to produce nitrogen at a purity of approximately 98%; in the second step this nitrogen is forced to pass into a second carbon molecular ...
Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. [ 1 ]

Electron capture ionization (ECI) is the ionization of a gas phase atom or molecule by attachment of an electron to create an ion of the form A −•.The reaction is + where the M over the arrow denotes that to conserve energy and momentum a third body is required (the molecularity of the reaction is three).
A post-column oxidation-reduction reactor is a chemical reactor that performs derivatization to improve the quantitative measurement of organic analytes.It is used in gas chromatography (GC), after the column and before a flame ionization detector (FID), to make the response factor of the detector uniform for all carbon-based species.
