METHOD FOR QUANTITATIVE DETERMINATION OF LYSINE ON INFRARED ANALYZERS BRUKER MPA OR BRUKER TANGO-R IN LYSINE SULFATE Russian patent published in 2024 - IPC G01N21/35 

FIELD: analytical chemistry.

SUBSTANCE: used in agricultural production, in particular in the feed industry. A method for the quantitative determination of lysine on Bruker MPA or Bruker Tango-R infrared analyzers in lysine sulfate involves determining the amino acid on the analyzer. Before starting work on the Bruker MPA or Bruker Tango-R infrared analyzers, the background is measured for 60 seconds, then lysine is selected on the display, after which the sample is placed on the bottom of two glasses of the same capacity, while the sample layer completely covers the bottom of each glass without the possibility of air bubbles and transparency, then the first glass is placed in the analyzer and measurement begins, after the message appears on the analyzer screen: “1 of 2 measurements taken. If you are ready to continue, click OK” place a second glass in the analyzer and start the analyzer again, after the second measurement the result of the measurement of lysine in lysine sulfate will be displayed on the screen.

EFFECT: ability to quickly and accurately quantify lysine in lysine sulfate without the use of chemical reagents and without sample preparation.
