title: Comparison of two mass-selective detectors with special reference to the analysis of residues of anabolics.
abstract: In the analysis of residues of anabolic agents the use of combined techniques, especially gas chromatography-mass spectrometry, is of increasing interest. When this method is used for the analysis of residues of anabolics it is very important to have a knowledge of the characteristics of the different types of apparatus on the market and to be sure that the results are not "apparatus-dependent". In this study two mass-selective detectors, the Hewlett-Packard 5970 and the ion trap detector 800, were compared by injecting the same samples of derivatized anabolics (standard solutions) into the two systems.
