Abstract
This Paper discusses the determination of 2-chloroethyl ethyl sulfide (CEES),by gas chromatography equipped with flame photometric detector (GC-FPD) (S-mode). The analysis was performed on HP-5 MS, 30 m x 0.32 mm capillary column with a 0.25 μm stationary film thickness using ultra pure nitrogen (99.9999%) as a carrier gas at 25 psi constant pressure. The method has been optimized. Factors affecting quantization of CEES such as injector temperature, carrier gas inlet pressure, air to hydrogen ratios and initial temperature program have been studied to get the best sensitivity, minimum delectability, dynamic range, linear range and noise. The linear ranges was (0.15 – 10) ngSand limit of detection was (0.15) ng/ml. The relative standard deviation (RSD %) was 1.59 % (n = 5), precision was over 99%. The method is precise, reproducible and non linear over this range of concentration. It can be recommended as a suitable method for the quantification of (CEES).
