| 520 | 3 |a“This investigation concerns the quantitative direct X-ray determination of quartz and pyrite in airborne mine dusts. A new technique developed by Leroux and Powers has been successfully applied and some new details have been found. The method provides reproducible analyses of quartz and pyrite in dust samples. When the calibration curves of the pure components have been made and certain sources of error are kept within appropriate limits, quartz and pyrite can be determined down to 30 μg/cm2 when deposited on appropriate filters"--Abstract, p. i. |
