Abstract

Abstract:

The method for analysing and measuring the benzene series(BTEX) including benzene,ethylbenzene,o-xylene,m-xylene,and p-xylene is established with gas chromatography,the capillary column and HP-5 detector.The precision and stability of the instrument was verified.The minimum detection limit of benzene,ethylbenzene,o-xylene,m-xylene,and p-xylene with Agilent7890B (with FID flame detector) was identified to be 1.68,2.17,2.018,2.021,1.256 μg/L respectively, This research establishes a basis for the determination of the BTEX concentration in air by GC.

Key words: GC, BTEX, precision, detection limit, stability
