FIELD: chemistry.
SUBSTANCE: method of spectral determining the microelement composition of viscous organic liquids consists in the fact that a small sample volume is subjected to analysis, which is previously mineralized by the action of a small volume of concentrated nitric acid upon heating. Sample preparation takes place at the end of the electrode to produce a dry residue of the sample, which is analyzed by spectral methods. The quantitative estimation is made on calibration schedules.
EFFECT: reduction of time and simplification of sample preparation, reduction of mass of analyzed sample and used reagents, increase of sensitivity, increase of reliability of results.
