Abstract
Low concentration of volatile organic components (VOC) usually need to be condensed before analyzing them by using gas chromatography (GC). NeedlExTM is a recently developed needle for adsorbing VOC. Gas components are easily adsorbed and condensed while passing through the adsorbents in the needle.
This paper describes the successful results of trying to adsorb and analyze light mineral oils by the use of NeedlExTM. They are often used for arson cases. The gas phase of soil containing gasoline, kerosene or gas oil was adsorbed using NeedlExTM, and was analyzed by GC. Through easy procedures, the VOC of their oils were efficiently condensed. Furthermore, NeedlExTM was successfully applied to adsorb and analyze kerosene contained in the clothes of a fire victim by using GC. NeedlExTM was found to be a useful device for the adsorption and analysis of light mineral oils.
