Possibilities for confirmatory analysis of some beta-agonists using two different derivatives simultaneously.
A previously described method for the confirmatory analysis of clenbuterol with chemical ionization GC-MS was extended to fit more beta-agonists. The method has been used routinely for about one year and a large number of samples have been analysed according to the described procedure. This paper summarizes the results obtained with this method with regard to clenbuterol and furthermore discussion is focused on applicability to beta-agonists other than clenbuterol with respect to the European Community requirements for confirmatory analysis.
