Abstract
A method is described for the direct X-ray diffraction analysis of alpha quartz in airborne dust samples from sandblasting operations. The samples are collected on Millipore organic membrane filters, using a gravimetric dust sampler. The filters are weighed to determine total weight of dust and then placed in a specially modified sample spinner. The intensity of the quartz diffraction peak is determined by measuring the area under the peak. The percentage of alpha quartz in the sample is found by comparing the intensity to a previously prepared calibration curve. The time savings achieved by eliminating prior sample preparation procedures and directly analyzing the sample filters facilitates massive screening studies of silicosis hazards in industrial operations.
