[An automated device for x-ray fluorescence analysis and its use in space and clinical medicine]. 1988

E G Biriukov, and G I Borisov, and Iu V Fedorov, and ZhidkovVV, and V I Lobachik

An experimental unit for radiofluorescent analysis using the REIS-I x-ray emitter, a Si (Li) detector, an analyser with the NOIKA LP-4900 microprocessor and appropriate soft ware was devised for a study of some aspects of metabolism and kinetics of a number of electrolytes playing an important role in the state of water-salt homeostasis of the organism of man and animals. Methodological approaches to quantitative determination of the native content of plasma trace elements and macrocells: S, Cl, K, Ca and stable bromine administered for determination of extracellular fluid volume--were developed. This method can be used for determination of quantitative indices of the above functions in healthy men and animals during outer space flights, ground mock-up experiments, for clinical investigations in diagnosis of subpathological conditions and for control of therapeutic efficacy.

D013052 Spectrometry, X-Ray Emission The spectrometric analysis of fluorescent X-RAYS, i.e. X-rays emitted after bombarding matter with high energy particles such as PROTONS; ELECTRONS; or higher energy X-rays. Identification of ELEMENTS by this technique is based on the specific type of X-rays that are emitted which are characteristic of the specific elements in the material being analyzed. The characteristic X-rays are distinguished and/or quantified by either wavelength dispersive or energy dispersive methods.
