Comparison of the Coulson and Hall electrolytic conductivity detectors for the determination of nitrogen-containing pesticides

Effect of Three Tillage Systems on the Persistence of Atrazine

“…Analysis utilizing GLC. The analysis of the samples utilized a gas liquid chromatograph (GLC)3 as described by Wilson and Cochran (10).…”

The Nitrogen Detector in Gas Chromatography

“…Response vs. furnace temperature for the detector (Model 310 Hall Electrolytic Conductivity Detector) operated in the catalytic reductive mode using a 2-mm I.D. quartz reaction tube containing a nickel wire catalyst bundle and a strontium hydroxide scrubber was investigated by Wilson and Cochrane, 76 Hall, 73 and Pape et al 77 Atrazine was used as a test compound by Wilson and Cochrane, and a mixture of atrazine, simazine, and chloroisopropyl carbonate (CIPC) was used by Hall. A wide variety of nitrogencontaining drugs was studied by Pape et al Response was found to increase rapidly from about 700°C to a maximum at 850 to 900°C for all compounds.…”

Pesticide residues

“…Wilson and Cochrane (385) compared the Coulson and Hall electrolytic conductivity detectors for the determination of nitrogen-containing pesticides. These authors found that the Hall detector had about seven times the sensitivity of the Coulson detector.…”
