Potassium chloride thermionic

Ives and Guiflfrida ° investigated the applicability of the potassium chloride thermionic detector and the flame ionization detector to the determination of organoarsenic compounds in the presence of organophosphorus and nitrogen-containing compounds.

Gas chromatography The AOAC method for the analysis of caffeine by GC uses a packed glass column, 6 ft ( 180 cm) in length by 4 mm ID, packed with 10% DC-200 oil on 80-100 mesh Gas Chrom Q, using nitrogen carrier gas and a thermionic potassium chloride detector. The injector temperature is 220°C, the column temperature is 190°C, and the detector temperature is 220°C. A wide variety of column-packing materials and detection modes can be used. For example, separation of caffeine, theophylline, and theobromine can be achieved with...
