Equipment for sampling and work-up for analysis of PAH and other organic compounds, and hydrogen fluoride and sulphur oxides |
摘要 |
Equipment samples and processes for analysis PAH and other organic compounds, as well as hydrogen fluoride and sulphur oxides in air and in gas in production equipment. The equipment comprises a layered adsorption device 1 in which the adsorbents are dry. During sampling, the adsorption device 1 is connected at its upper end to a probe 8, which is brought into contact with the object to be sampled, and connected at its lower end to a gel box 10, a pump 9 and a gas clock 12, in series. After sampling, the adsorption device 1 may be connected directly to an extraction apparatus 11 for the processing of the sample.
