Air Monitoring: New Advances in Sampling and Detection

Figure 3

Main image: analysis of 40 mL of a 1 ppm 62-component “US EPA TO-15 air toxics” standard (i.e., a heavily overloaded sample) using a CIA-Advantage system, (Markes International Ltd). Inset: Expansion of the peaks for 1,2,4-trichlorobenzene and hexachloro-1,3-butadiene, showing subsequent analysis of a 500 mL nitrogen blank demonstrating very low carryover even under extreme conditions and for these late-eluting components (method conditions are shown in Table 2).
