Abstract
An i.r. method is described for the direct analysis of quartz in respirable dusts sampled on Gelman VM-1 filters. The reliability of the method for the analysis of coalmine dusts is assessed by comparison with the potassium bromide disc technique described in Part I. The direct method is both rapid and simple. Although less sensitive than the disc technique, it offers a considerable advantage where a speedy analysis is of more value than ultimate precision.Keywords
