METHOD FOR LASER ATOMIC EMISSION SPECTRAL ANALYSIS OF HAIR Russian patent published in 2016 - IPC G01N21/73 

FIELD: medicine.

SUBSTANCE: invention relates to spectral analysis and can be used in biological and clinical diagnostic laboratories for monitoring state of health of patients. Method for laser nuclear emission spectral analysis of hair includes treatment of analysed sample at stages of water washing, drying and thermal treatment at next tool method of determining content of metals using pilot laser for accurate selection of radiation zone of inspected sample. At that, during whole process of treatment analysed sample controlled part stays in capsule volume less than 10 mql, and stages of heat treatment are combined and reduced to few minutes at state of sample to its carbonisation at 285 ± 5 °C, in process of which recorded losses of volatile components contained in exhaust gases with hydrocarbon matrix, using their source of excitation of six-jet plasmatron that is followed by laser irradiation of charred test in subsequent staged treatment spectrum analytic signals obtained during implementation of both methods of spectra excitation.

EFFECT: higher accuracy of hair analysis due to control chemical composition of exhaust gases.
