摘 要: | 采用活性炭吸附、溶剂解吸法或热脱附(Tenax做吸附剂)法前处理、气相色谱仪(FID检测器)或气相色谱/质谱联用仪检测法对空气中苯系物进行定性、定量分析,并对试验方法和分析结果加以讨论。试验表明,热脱附前处理-气相色谱/质谱联用仪检测法是一种灵敏度高、回收率高、精密度高的定量分析方法。

Abstract: | By using activated carbon adsorption solvent desorption method,thermal desorption pretreatment(Tenax as the absorbent),and GC or GC-MS for detecting airborne BTEX,qualitative and quantitative analysis is conducted.Then,the experiment methods and analysis results are discussed.Results show that thermal desorption pretreatment with GC/MS selected ion monitoring is a good quantitative analysis method that has high sensitivity,high accuracy and high recovery rate. |
