1.1 ,This test method describes the sampling and continuous analysis of ozone (O3) in the atmosphere at concentrations ranging from 10 to 2000 μ,g/m3 of O3 in air (5 ppb(v) to 1 ppm(v)).
1.1.1 ,The test method is limited to applications by its sensitivity to interferences as described in Section 6. The interference sensitivities may limit its use for ambient and workplace atmospheres.
