THE CHARACTERIZATION OF COMPLEX-MIXTURES BY FIELD DESORPTION TANDEM MASS-SPECTROMETRY

This paper shows the first application of field desorption-tandem mass spectrometry (FD-MS/MS) in a hybrid sector, orthogonal acceleration t ime-of-flight mass spectrometer, This instrumentation has significant advantages in detection limits for MS/MS experiments over four sector mass spectrometers. This is important when using FD ionization from wh ich low ion currents are generated. Data are shown from a few classes of industrial compounds and the proposed fragmentation pathways are de scribed. (C) 1998 John Wiley & Sons, Ltd.
