| titleOfInvention | The method being measured to the benzene and benzene homologues in PUR using microwave abstracting Gas Chromatography-mass Spectrometry |
| abstract | Method the present invention relates to be measured to the benzene and benzene homologues in PUR using microwave abstracting Gas Chromatography-mass Spectrometry, it is comprised the following steps：In closed container, using Microwave Assisted Extraction Technique, the benzene and benzene homologues in PUR are extracted with solvent；After sample after extraction is cooled to normal temperature, centrifugation is placed in a centrifuge, takes supernatant liquor to be measured；C. the sample after extraction is analyzed using Gas Chromatography-mass Spectrometry, selects ion detection, inner mark method ration obtains the testing result of benzene and benzene homologues in PUR.For the specialized character of PUR in the present invention, processed before being carried out to PUR sample using microwave-assisted extraction technique in the closed container, and the benzene and benzene homologues that combined gas chromatography mass spectrometry Accurate Determining wherein contains, detection limit and quantitative limit are satisfied by real requirement. |
