Patent

CA 2104409

The invention concerns equipment for sampling and processing for analysis of 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 the sampling, the adsorption device 1 may be connected directly to the extraction apparatus 11 for the processing of the sample.

L'invention porte sur du matériel d'échantillonnage et de traitement pour l'analyse des HAP et d'autres composés organiques, ainsi que du fluorure d'hydrogène et des oxydes de soufre dans l'air et les gaz d'installations de production. Le matériel comprend un dispositif d'adsorption stratifié 1, dans lequel les adsorbants sont secs. Lors de l'échantillonnage, le dispositif 1 est connecté par son extrémité supérieure à une sonde 8, qui est amenée en contact avec l'objet à échantillonner, et par son extrémité inférieure à une boîte de gel 10, une pompe 9 et un compteur à gaz 12, disposés en série. Après l'échantillonnage, le dispositif d'adsorption peut être connecté directement à l'appareil d'extraction 11 pour le traitement de l'échantillon.
