[Laser mass-spectrometric medical microanalysis]

Quantitative analyses of the whole microcomposition at a time without using the standards are shown to be realizable by the laser mass-spectrometry carried out on the domestic device EMAL-2. The techniques of sample preparation are simple and may be applied to analyze the wide range of medical and biological specimens. From the obtained results it is obvious that the mass-spectrometric method is useful in microanalyzing element compositions of medical and biological specimens.
