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

FIELD: analytical chemistry.

SUBSTANCE: invention can be used in agricultural production, in particular in the feed industry. A method of the quantitative determination of threonine on Bruker MPA or Bruker Tango-R infrared analyzers in threonine involves determining the amino acid on the analyzer. Before starting the work on the Bruker MPA or Bruker Tango-R infrared analyzers, the background is measured for 60 seconds, then threonine 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. When the following 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 threonine in threonine sulfate will be displayed on the screen.

EFFECT: ability to quickly and accurately quantify threonine in feed threonine without the use of any chemical reagents and without any sample preparation.
