Comparison of oil sorbent/vial kit for sampling and preservation of liquid volatile petroleum

Abstract

An oil sorbent sheet made of nonwoven polypropylene fiber and a vial with screw cap were assessed as the test kit for sampling and preservation of liquid volatile petroleum samples in the forensic science field. Motor gasoline and kerosene were used as the petroleum samples. The analytical results of headspace gas chromatograph mass spectrometer (HSGCMS) revealed that this kit was much more retentive and stainless for petroleum samples than the gauze and plastic bag used in the conventional kit. This kit is suitable for sampling and preservation of petroleum samples obtained at crime scenes or floating on water. Petroleum sampled and preserved with this kit can be introduced directly into the auto sampler and analyzed promptly by HSGCMS.
