Abstract
A method is described for the quantification of major volatile substances in human breath without preconcentration. Methanol, ethanol, acetaldehyde and acetone are well separated by porous-layer open-tubular column gas chromatography. Low-level detection was possible by means of an ion trap detector. Halothane has been used as internal standard.
摘要
描述了一种无需预浓缩即可定量分析人体呼出气体中主要挥发性物质的方法。甲醇、乙醇、乙醛和丙酮通过多孔层开管柱气相色谱法得到很好的分离。借助离子阱检测器可进行低水平检测。已使用氟烷作为内标。
