Determination of Short Chain Chlorinated Paraffins by GC-Chloridine Attchment Chemical Ionization in Hyphenation with Low Resolution MS

GC with chloridion attachment chemical ionization in hyphenation with low resolution MS was applied to the determination of short chain chlorinated paraffins (SCCP). Vapour over a mixed solvent of n-hexane and dichloromethane, which was used as the reagent gas, was introduced directly into the ion-source through a capillary chromatographic column. Values of recovery found by standard addition method were in the range of 84.9%-95.4%, and RSD′s in the range of 15%-18%. The proposed method was applied to the analysis of some substantial samples. As compared with the carbon skeleton method, values of relative errors found were ranged from 3.67% to 7.69% for samples with low mMCCP/mSCCP ratios, and was 77.9% for samples with high mMCCP/mSCCP ratios.
