| Resumen |
The method was developed with particular reference to the foundry industry, where determination of quartz in small dust samples is often required. Analysis is done directly on a collecting cellulose ester membrane filter. Quantitation is achieved by measurement of the quartz line intensities with a digital integrator and comparison of these values with calibration standards. Overall precision is 8%. Accuracy of quartz analysis of foundry dusts was within 10% at the 1-10mg level of total loading. Detection limit for quartz was <0.1mg. |
