1 Scope of application

1.1 This standard is applicable to the determination of chlorobenzene compounds from organized and unorganized emissions from stationary sources of atmospheric pollution.

1.2 When the sampling volume is 30L, the desorption volume is 3ml, and the chromatographic injection is 1μL, the detection limit of the method is shown in Table 1.

                             Table 1 Detection limit of the method/(mg/m3)


      The detection limits of the methods vary when the instruments used are different.
