Carrier gas purity is essential in any application requiring extreme sensitivity. Impurities limit detector sensitivity and can even destroy capillary columns. The Valco nitrogen purifier provides "point-of-use" purification to sub-ppm levels of reactive gaseous impurities.
The miniature version is designed to be installed in a gas chromatograph's flow path immediately upstream of the injector. The NPM will remove any contaminants introduced by flow controllers, elastomeric tube seals, pressure regulators, crude traps, or other system components that are not completely clean and leak-tight.
