An efficient ion transport system that interfaces external ion sources with a commercial dual-cell Fourier transform mass spectrometry (FTMS) system so as to retain maximum experimental flexibility has been constructed. Electrostatic lenses were used for ion transfer with potentials less than 200 V
Application of FT LMMS to inorganic compounds offers the advantage of direct speciation. This means that signals which refer to intact analyte molecules are detected. Cumnt concepts of desorption and ionization in LMMS are mainly based on time-of-llight data and hence on ions formed during the laser
