Abstract
The Coulson electrolytic conductivity detector for nitrogen compounds has been found to be sensitive, specific, reliable, and easy to use. The detection limit has been extended down to 0.1 nanogram of organic nitrogen with a selectivity of 10,000:1 or more against organic chlorine, sulfur, phosphorus, and carbon. The detector can be operated for extended trouble-free periods with only routine maintenance. The wide distribution of organic nitrogen compounds does not appear to present any serious obstacles to the general applicability of this detector to pesticide-residue analyses of crops in the range of 0.02 ppm.Keywords
