ABSTRACT
The results of an experimental study dealing with the elementary composition of bone tissue by using the method of laser mass spectrometry are described in the paper. The method ensures the quantification of concentration values of all elements from the Mendeleev periodic table that can be made within an extensive dynamic range, which makes it promising in the forensic medical identification.

Laser mass spectrometric analysis of a biomedical sample was made on exposure to laser radiation at lambda 2 = 532 nm. The parameters of laser radiation and mass spectra were comparatively analyzed by using the basic and second harmonics of aluminum-yttrium-garnet-based laser. The sensitivity of laser mass spectrometry of biomedical samples is increased.
