Development of Synthetic Standard Samples for Trace Analysis of Air Particulates

Source

Synthetic, “homogeneous,” and particulate standard samples in the form of deposits on filters have been developed for use in quality control of analytical methods and for calibration of X-ray emission spectrometers.

The standards for X-ray emission spectrometer calibration comprise membrane filters with single element or multielement solutions homogeneously deposited and dried, and 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. The standards for sulfates, nitrates, and volatile trace elements were deposited in the form of solutions on glass fiber filters and dried. The standards for nonvolatile trace elements were prepared from -10-μm quartz powder spiked with compounds of the elements and deposited from air suspension.
