Abstract
This report describes development of a technique and apparatus for determining the concentration of respirable quartz, kaolinite, and calcite directly on individual personal dust sampler filters using infrared absorption spectrometry. The sample filter is placed in the sample beam of a double-beam spectrometer and rotated to average nonuniform deposits; a blank filter is placed in the reference beam. The analog output of the spectrometer is digitized and fed to a minicomputer that performs all necessary calculations including correction for the major interference (kaolinite) in the determination of quartz. This method permits rapid and precise determination of the exposure of individual miners to respirable quartz dust.
