Foodborne stimulants test large instruments show their skills

Between April and June of this year, the National Anti-Doping Center of the State Sports General Administration carried out 4,768 inspections.

In August 2012, the Dandong municipal government invested 2.8 million yuan to purchase a liquid-liquid coupling instrument that was specifically used for corroboration testing of illegally added substances such as clenbuterol, which enabled the Bureau of Animal Husbandry to improve inspection methods and improve inspection capabilities. Great progress. In the meantime, UPLC/QUARTE tandem mass spectrometry instrument has played an important role as an indispensable instrument for the detection of food-borne stimulants, providing a guarantee for confirmatory testing.
