FIELD: analytical methods in food industry and biotechnology.
SUBSTANCE: object of invention is to determine contents of cations, amines, anions of organic and inorganic acids in various media in food, alcoholic beverage and soft drink industries. Working electrolyte for electrophoretic determination of ions is composed of, mmole/L: histidine 25-35, 2-morpholinoethanesulfonic acid 100-140, a Crown ether 1.5-2.5, Triton X-100 0.02-0.50, and water - the rest.
EFFECT: enabled simultaneous determination of cations, amines, anions of organic and inorganic acids in various media.
