METHOD FOR DETERMINATION OF PAHs AND PCBs IN SAMPLE BY GC/MS WITH SPME

摘要

The invention, SPME (Solid Phase Microextraction, the solid trace extraction) fiber for the above sample water head space (headspace: HS) with a possible fixed-bed adsorption of the analytes is covered by mounting exposed to water sample or a biological sample in the PAHs (polyaromatic hydrocarbons) and PCBs (polychlorinated biphenyls) adsorption and the PAHs and PCBs are adsorbed fiber for high temperature gas chromatography inlet in the desorption was then, gas chromatography / mass spectrometry analysis of steps, including that the sample of It relates to a method for simultaneous detection PAHs and PCBs present in trace amounts. The detection method of the present invention is also applicable to biological samples comprising a more complex matrix, such as urine or blood, in addition to typical water samples, the sensitivity is excellent, because the pre-treatment process without the use of organic solvent required beneficial environmental and economic Do.
