Abstract:
A pulsed ion source has been developed supplying two slightly shifted mass spectra for every single ionization pulse, e.g., by laser induced resonance enhanced multiphoton ionization (REMPI). This allows comparison of ion signals with a difference of relative intensity in the percent and sub-percent range. Such small differences may be due to small changes of gas compn. or of ionization conditions and usually are hidden by pulse to pulse fluctuations of laser pulse energy, gas d., elec. fields,...     »
