Development of synthetic standard samples for trace analysis of air particulates
Abstract
Synthetic, 'homogeneous,' and particulate standard samples in the form of deposites on filters have been developed for use in quality control of analytical methods and for calibration of X-ray emission spectrometers. The standards for spectrometer calibration comprise membrane filters with single-element or multielement solutions homogeneously deposited and dried, as well as membrane filters with known amounts of single-mineral powders of well-defined particle-size ranges deposited and fixed on them. For quality control of analytical methods and laboratories, synthetic standards for sulfates, nitrates, and trace elements have been developed. These standards were deposited in the form of solutions on glass-fiber filters and dried. Standards for nonvolatile trace elements were prepared from quartz powder with particle sizes of less than 10 microns spiked with compounds of the elements and deposited from air suspension.
