Application of X-Ray Emission Spectrography to Air-Borne Dusts in Industrial Hygiene Studies

Energy dispersive x-ray fluorescence analysis of air particulates in Texas

“…X-ray fluorescence spectroscopy has been used for air particulate analysis by a few workers (Hirt et al, 1956;Bumsted, 1964). However, the conventional method, using a crystal spectrometer and sequential counting of each element has not found broad application in routine air particulate analysis.…”

X-Ray Absorption and Emission

“…This name is given to the spectrographs in which an analytical line is excited by an electron beam in a volume that may approach 1-micron cube. These instruments permit of reliable and convenient point-to-point exploration on a micron scale, and they can thus provide information attainable 101,117,122,159,160,163,182,186,192,193,198,202,218,220) Krypton in no other way. The instrument invented by Castaing {132) is now offered commercially {104), and two recent articles {40, 173) give a variety of interesting applications.…”

“…Although these applications are primarily structural rather than analytical, the discussion is worthwhile reading for the analyst. Four excellent reviews of this book have appeared (16,16,101,104).…”

Air Pollution

“…An extension in the range of the technique is represented by the appearance of fluorescent x-ray spectrography, which has been claimed superior to chemical and spectrochemical methods in determination of trace amounts of iron, nickel, and vanadium on catalysts (108). An x-ray photoelectron spectrometer for chemical analysis has also come into use (414)• Applications of x-ray emission spectrography to analysis of air-borne dusts have been made (190). The voluminous literature on special applications and new developments in techniques of spectroscopy is comprehensively reviewed each year by the American Chemical Society in Analytical Chemistry.…”
