COMPARISON OF MASS-SPECTROMETRIC TECHNIQUES FOR THE ANALYSIS OF TRACE AMOUNTS OF 1-METHYLAMINOANTHRAQUINONE, USED AS SMOKE DYE IN EXPLODING MONEY SUITCASES

Results are presented for different chromatographic and mass spectrometric methods of analysis of the smoke dye MAAQ. When applying gas chromatography various mass spectrometric (ionization) methods can be employed to reach the low picogram range, but for difficult samples full of other dirt preference has to be given to an MS-MS method in the daughter (negative) ion mode. The results of LC-thermospray-MS and LC-thermospray-MS-MS are somewhat less sensitive.
