【Abstract】 This paper puts forword a method of determining trimethylbenzene the air of workshop by GC. Trimethylbenzene is collected by an injector and isolated by Apiezon grease L column. It is detected with a hydrogen flame ionization detector. Coefficient of variation of this method is less than 10% . The rate of recovery range is from 96.7% to 101.3% .更多还原
