RATIONALE Doping analysis is a two‐step process consisting of screening step for prohibited substances and confirmation to verify the presence specific found during screening. The entire must be performed within limited time period, but traditional procedures commonly employ separate analytical methods each class being screened thus require great deal human resources instrumentation. A single simple rapid multiresidue method that could accommodate multiple classes would extraordinarily...
