Electrons are supplied from a 63 Ni filling the detector cell. A current is generated in the cell.
Electronegative compounds capture electrons resulting in a reduction in the current.
The amount of current loss is indirectly measured and a signal is generated. However, nitrogen also results in greater nois, so sensitivityis not significantly chnaged. Antraquinone response as a function of detector temperature. The chromatographic conditions were the same above mentioned. Always precondition the column before connection to the detector.
