Centro de Documentacion de Fundación MAPFRE - Generation of hexahydrophthalic anhydride atmospheres in a controlled human-use test chamber

Notas: Sumario: The authors report a method, based on the permeation principle, for the generation of low air concentrations of hexahydrophthalic anhydride (HHPA) in an exposure chamber. The losses of HHPA in the chamber have been evaluated and a method for the continuous monitoring of the HHPA concentrations, based on Fourier-transform infrared spectroscopy, is described. In addition, an improved method for the determination of the sum of HHPA and HHP acid is reportedRegistros relacionados: En: American Industrial Hygiene Association journal. - Fairfax, Virginia. - Vol. 55, nº 4, April 1994 ; p. 330-338Materia / lugar / evento: Higiene industrial Contaminación atmosférica Ambiente de trabajo Contaminantes químicos Anhídridos Anhídrido hexahidroftálico Métodos analíticos Muestreos Otros autores: Welinder, Hans
