摘要
通过固相微萃取气相色谱质谱法定性或定量检测负压体系中十二种微量挥发性有机物,如乙醇、二氯甲烷、乙酸乙酯、正己烷、甲苯等,检出范围1.6×10-3μg·L-1~1.7μg·L-1。
Twelve micro volatile organic compounds(ethanol, dichloromethane, acetic ether, n-hexane, toluene and so on) were determined qualitatively or quantitatively in negative pressure system by solid-phase micro extraction gas chromatography-mass spectrometric method. The detection limits varied in the range of 1.6×10-3μg·L-1~1.7μg·L-1.
