Generation of hexahydrophthalic anhydride atmospheres in a controlled human-use test chamber / Bo A.G. Jönsson, Hans Welinder, Gunnar Skarping
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 reported
