The use of performance enhancing drugs in sports is prohibited. For the detection of
misuse of such substances gas chromatography or liquid chromatography coupled
to mass spectrometry are the most frequently used detection techniques. In this
work the development and validation of a fast gas chromatography tandem mass
spectrometric method for the detection of a wide range of doping agents was
developed and validated.
The method is capable to detect quantitatively 13 endogenous steroids (the steroid
profile), 19-norandrosterone, salbutamol and 11-nor-9-tetrahydrocannabinol.9carboxylic acid in the applicable ranges and to detect qualitatively over 140 substances in accordance with the minimum required performance levels of the World Anti-Doping Agency in 1 ml of urine. The classes of substances included in the method are anabolic steroids,
β2-agonists, stimulants, narcotics, hormone antagonists and modulators and beta-blockers. At these levels the identification according to WADA’s criteria for identification using
chromatography and mass spectrometry was achieved.
Moreover, by using a short capillary column and hydrogen as a carrier gas the run
time of the method is less than 8 min. This means the method is –in general- three times faster than most methods used routinely for the analysis of doping control samples. Hence, the method allows for a high throughput allowing faster reporting times and reduced instrument costs.
Hence, this method is capable of detecting and confirming a wide range of doping substances at very low concentration in a short time. Such improvements increase the efficiency in anti-doping laboratories and allow for faster reporting. Additionally,
the use of multiple internal standards allows for the evaluation of the quality of
every single step in the analytical methodology.
