## Abstract 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 μL of extract containing 15 organochlorine pesticides and separation of all analytes in less than 8 minutes.

✦ Synopsis
Abstract
This study describes an SPE coupled with large volume injection (LVI) analytical method for the analysis of organochlorine pesticides, BHC (α, β, Δ), aldrin, endosulfan (α, β), endrin, dieldrin, and DDT, from aqueous samples. Determination was carried out by GC with MS. The LODs of organochlorine pesticides were determined at 10 ng/L concentration levels, and the results show that SPE‐LVI‐GC/MS has the potential to accurately determine organochlorine pesticides in water, as it avoids analyte classes in the various steps of a typical extraction procedure.
