METHOD OF ATOMIC EMISSION ANALYSIS OF SOLUTIONS Russian patent published in 2019 - IPC G01N21/74 G01N33/18 B82Y35/00 

FIELD: chemistry.

SUBSTANCE: invention relates to analytical chemistry, can be used for instrumental analysis of solutions – atomic emission spectrometry. In the method of atomic emission analysis of solutions, involving introduction of an organic additive into the initial analyzed solution before its spraying into a plasma atomiser, additive used is hydrosol nanoionite with particle size in range of 10–300 nm and initial concentration of 1–100 mmol/l by functional groups, wherein 10 ml of the analyzed solution is added from 0.001 ml to 1 ml of hydrosol to create in the analyzed solution concentration of nanoionite 0.01–10.0 mmol/l by functional groups.

EFFECT: higher sensitivity of analysis and reduced costs due to use of small amounts of additives in analyzed solution and failure of complex sample preparation relatively large quantities of analyzed solutions.
