Study on the feasibility of coupling large-volume injection to fast gas chromatography with mass spectrometric detection for analysis of organochlorine pesticides

A combined use of programmable temperature vaporisation injector, fast oven temperature ramp, 0.1 mm ID analytical column and hydrogen carrier gas enabled injection of up to 20 muL of extract containing 15 organochlorine pesticides and separation of all analytes in less than 8 minutes.
