Title: A Diffusive sampler of gaseous pollutants by collection in liquid media / Bengt-Olov Hallberg and Jan RudlingAuthor: Hallberg, Bengt-Olov
Notes: Sumario: A diffusive sampler to be used with an absorbing solution for the collection of worplace pollutants is described. It is constructed of polytetrafluoroethylene and the diffusion is controlled by a number of small chanels. The sampler has been evaluated in the laboratory using ammonia and sulphur dioxide as test gases. The sampling rate was constant for different air concentrations and it agreed well with theoretical calculations. No effects from humidity were seen during sampling and no sample loss was observed after storage for up to 4 weeksRelated records: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 1, 1989 ; p. 61-68Materia / lugar / evento: Higiene industrial Contaminantes químicos Contaminantes gaseosos Ambiente de trabajo Contaminación atmosférica Control de la contaminación Gases Muestreador Muestreos Otros autores: Rudling, Jan
