Determination of cyclic organic acid anhydrides in air using gas chromatography .2. Sampling and determination of hexahydrophthalic anhydride, methylhexahydrophthalic anhydride, tetrahydrophthalic anhydride and octenylsuccinic anhydride
Methods for sampling and determination of four organic acid anhydrides are described. The methods were validated in a standard atmosphere and in the work environment. Hexahydrophthalic anhydride (HHPA), methylhexahydrophthalic anhydride (MHHPA), tetrahydrophthalic anhydride (THPA) and octenylsuccinic anhydride (OSA) were sampled using Tenax and Amberlite XAD-2 solid sorbents and determined by GC w
