American scientists have learned to detect doping in new ways. The accuracy of the test was increased 1,000 times. Despite the prohibition, doping is widely used in modern professional sports in order to improve athletic performance.
The new method allows you to detect steroids and stimulants in minimal concentrations. The technology is inexpensive and works on existing equipment, according to the British BBC news service.
The results of the study were presented at a meeting of the American Chemical Society (ACS).
In contrast to the widely used mass spectrometry, a new method of analysis involves the exposure of a urine sample to an electron beam that turns atoms into charged particles. Then these particles pass through a spectrometer, where they are “weighed” by a magnetic field. Knowing the weight of many steroids, scientists will not be hard to detect doping with high speed and accuracy.
Researchers at the University of Texas at Arlington reported that a system called Paired Ion Electrospray Ionisation (PIESI) uses a reagent to bind tiny particles of steroid or amphetamine to make them visible to the detector. According to the author of the study, Daniel Armstrong, we are talking about trillionths. The new system is 10-1000 times more accurate than any other known systems, depending on the analyte, he notes.
In the laboratory, the system revealed steroids, stimulants, alcohol and depressants. Given the commercial availability of the binding agent, scientists hope to adapt the system to existing methods of detecting doping quickly and cost-effectively.
