Abstract
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.
