Sampling and analysis of airborne methylbromide

, : Sampling and analysis of airborne methylbromide. Chromatographia 27(1-2): 37-43

Air sampling of methylbromide using 900 mg HBr-treated activated charcoal tubes, followed by solvent desorption and FID or ECD chromatographic analysis makes it possible to evaluate concentrations ranging from 0.2 ppm (1 mg .times. m-3) to 250 ppm (1 g .times. m-3) at ambient temperature even with a high hygrometric level. Thermal desorption does not lead to satisfactory results.

However, the duration of these cycles remains uncertain, as well as whether...
