Semivolatile organic chemical sampling and extraction transfer method and apparati |
摘要 |
<p>One way of practicing the method of the invention is to follow these steps, not necessarily in the disclosed sequence: (1) providing a hot gas spike apparatus to load one or more diffusion denuders with a compound selected from the group consisting of a calibration standard, an internal standard, and a surrogate standard compound in a solvent carrier; (2) pulling one or more samples of ambient atmosphere through at least one of the diffusion denuders in a multicapillary collection device; (3) extracting analytes from at least one of the diffusion denuders in an analyte transfer apparatus or from a filter using an extraction device; (4) optionally cleaning up gaseous extracts or extracts of tilters using chromatography, and transferring the collected analytes into an analytical device. To practice the method, an apparatus is disclosed that has a hot gas spike component, a high-flow multicapillary collection device and an analyte transfer apparatus.</p> |
