Abstract
A 63Ni electron-capture detector (ECD) ie used after capillary column supercritical fluid chromatography (SFC) without any modification. Detection limits of nitro and halogenated compounds are found to be picograms and high femtograms, respectively. Detector linear dynamic range is three to four orders of magnitude for the studied compounds. Good sensitivities em obtained for a number of thermally labile pesticides (i.e. ones and phosphates) using SFC-ECD.Keywords
