| titleOfInvention | Using the method for SPME gas chromatography mass spectrometry examination sample Poisoning material |
| abstract | The present invention provides a kind of method of use SPME gas chromatography mass spectrometry examination sample Poisoning material.This method comprises the following steps：Sample is extracted using the mixed solution of water-miscible organic solvent and deionized water, extract solution is made；The extract solution is centrifuged, supernatant is collected and removes the organic solvent in supernatant, centrifuges again and collects supernatant, sample liquid is made；PDMS extracting heads are inserted in the sample liquid and carry out SPME, takes out in PDMS extracting heads, insertion gas chromatograph-mass spectrometer and is desorbed after extraction, desorption sample subsequently enters progress GC MS analyses in chromatographic column.The method of the present invention can be different to various structures in sample toxicant carry out quick, effectively detection, particularly one-time detection is that the examination to more than 60 kinds of toxicants can be achieved, detection efficiency is high, the fields such as forensic science is particularly suitable for use in, with good actual application value. |
