FIELD: chemistry.
SUBSTANCE: invention relates to analytical chemistry element analysis and can be used for laser-spark emission determination of beryllium in metal alloys and powders. Method is based on exposing surface of analysed sample to focused laser radiation with pulse duration of 240-250 mqs and pulse energy of 1.3-1.4 J. Laser spark luminescence analysis enables to pick out spectral lines of vapours of beryllium and identification of its spectral lines.
EFFECT: for determination of beryllium experimentally most sensitive laser emission lines of element in spectral range 310-321 nm are used.
