【摘要】：提出了用氣質(zhì)聯(lián)用儀測定工作場所氣體中有害物質(zhì)的檢測方法。對色譜條件進(jìn)行優(yōu)化,選擇Agilent HP-5MS色譜柱進(jìn)行分離,柱流速1mL/min,運行時間24min。所測22種物質(zhì)在0.1~0.5μg/mL之間線性關(guān)系良好,相關(guān)系數(shù)均大于0.999,方法能夠快速準(zhǔn)確的對工作場所常見的職業(yè)病危害因素進(jìn)行定性分析。在危險復(fù)雜的突發(fā)事故場所快速定性,彌補(bǔ)了現(xiàn)有職業(yè)衛(wèi)生國標(biāo)檢測方法在氣質(zhì)聯(lián)用技術(shù)上的缺失,充分發(fā)揮了GC-MS聯(lián)用技術(shù)具備的快速、簡便、準(zhǔn)確等優(yōu)點。
[Abstract]:A method for the determination of harmful substances in workplace gases by GC-MS was proposed. The chromatographic conditions were optimized and the Agilent HP-5MS column was selected for separation. The flow rate of the column was 1 mL / min and the running time was 24 min. There was a good linear relationship between 0. 1 渭 g/mL and 0. 5 渭 g/mL, and the correlation coefficients were all greater than 0. 999. The method could be used to analyze the occupational hazards in the workplace quickly and accurately. The rapid qualitative analysis in dangerous and complex accident sites makes up for the deficiency of the existing national standard testing methods of occupational health in the combined use of temperament and gives full play to the advantages of GC-MS combined technology such as rapidity simplicity accuracy and so on.
