| Abstract |
Aerosol and vapour MPDA and MDA are collected on an acid-coated, glass-fiber filter to stabilize them as their amine salts. The amines are extracted from the filter with a mixture of acetonitrile in aqueous base and then treated with acetic anhydride to form the diacetamide derivatives. The derivatives are analyzed by high performance liquid chromatography with UV detection. The method may be used with confidence to measure from 0.90 to 755µg of MPDA and/or 0.36 to 55µg of MDA in a total air volume of 200 to 630L, sampling at a rate of 1.5 to 2.0L/min. Collected samples remain stable on filters for at least 1 week before analysis. The method will not suffer from interference from high relative humidity or other process volatiles, including diglycidyl ether of bisphenyl [sic] A and bis(2,3-epoxycyclopentyl)ether. This method can be applied to most aromatic amines and is recommended for monitoring both ambient and workplace air. |
