Centro de Documentacion de Fundación MAPFRE - A Simple, sensitive technique for personal and environmental sampling and analysis of lead alkyl vapours in air

Notas: Sumario: A technique is described for collecting lead alkyl vapour in air by sampling through a small vapour adsorption tube packed with porous polymer beads. Volumes of at least 10.1 of air can be sampled without breakthrough losses, allowing 8-h shift sampling using one tube and low flow rate personal sampling pump. Tubes can be stored for several days without loss of sample; they can be analysed in 2 min. by heat desorption directly into an atomic absorption spectrometer burner. The analysis is specific for lead alkyls and detection limits are around 0.01 for TLV or 10-20 ng leadRegistros relacionados: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 1, March 1978 ; p. 33-38Materia / lugar / evento: Higiene industrial Contaminantes químicos Plomo tetraetilo Vapores Contaminación atmosférica Control de la contaminación Valores TLV Métodos de análisis Títulos secundários: Título: The Annals of occupational hygiene
