Phenylpiracetam(cas 77472-70-9) Detect:

After the end of the game within 1h, the selected athletes (usually obtain ranking, random selection does not get ranking.) In person accompanied to obtain urine sampling stations. Usually at least 75mL, dispensed two bottles, a bottle of about a sample of 50mL, 25mL about another bottle of B sample. A sample to be analyzed, the sample B is used for analysis review. In testing, A urine sample after the registration number, measuring some basic data, such as pH, specific gravity, color, size, with or without precipitation, then the urine sample is divided into several parts, into the line is detected after screening by the group, if it is negative then discarded. If illicit drugs will require further confirmed its presence in prohibited drugs, since the outer portion of anesthetics and stimulants are high boiling point, less volatile polar compound, when using GC or GC-MS detected, first by chemical derivatization, convert it into a low boiling point, less polar compound in order to achieve the purpose of detecting, by chemical derivatization may further improve the separation effect, increase detection sensitivity, but there are many variations derivation method, but also a variety of derivative reagents.

Why do people use Phenylpiracetam(cas 77472-70-9) in Olympic Games?

Huge economic interests prompted some coaches and athletes to rack their brains to seek new ways of prohibited drugs and prohibited methods other than to escape detection, and due to the continuous emergence of new drugs, which gave doping testing work put forward new demands and challenges. There are more isolated on the Olympic Games doping athletes, like the 1988 Seoul Olympics famous American sprinter transport.

In particular increased blood tests at the 2000 Sydney Olympics, urine blood test plus "double insurance", but it can't stop those who violate a ban, such as the Bulgarian weightlifter punished doping was recovered gold medal, but also because the Romanian gymnast failed urine test canceled the gold medal. From 1997 to 1999, China's domestic a total of 7089 cases, 52 positive cases, the positive rate was 0.51%. It should be noted, Some developed countries on the one hand in the continuing development of new drugs to fight doping testing, and indeed there are some athletes can not be detected in developed countries currently taking new stimulants to escape detection instruments, on the other hand they in turn they believe outdated drugs market, send someone down, "hell." Therefore, the fight against doping is a long and arduous task, especially analytical chemistry required to provide an updated, more effective analysis, testing methods, in order to maintain and carry forward the sacred Olympic spirit.
