Zusammenfassung: | The invention belongs to the technical field of environmental substance detection, and relates to an on-site rapid emergency monitoring method for rapidly determining isopropanol, n-propanol, ethyl acetate and tetrahydrofuran in an environmental sample. According to the method, a vehicle-mounted gas chromatography/mass spectrometer with a headspace assembly is adopted, reagent water is used as a solvent, a medium-polarity chromatographic column of DB-624 LTM is adopted for separation, an ion (SIM) scanning mode is selected, and dichloromethane d2 is used as an internal standard for quantification.
本发明属于环境物质检测技术领域,涉及一种快速测定环境样品中异丙醇、正丙醇、乙酸乙酯和四氢呋喃的现场快速应急监测方法。采用配备顶空组件的车载气相色谱/质谱仪,以试剂水为溶剂,采用DB-624 LTM中等极性色谱柱分离、选择离子(SIM)扫描方式、二氯甲烷-d2为内标定量。 |
