The sensitivity of all ion trap mass spectrometry (ITMS) methods is dependent on the trapping efficiency of the instrument. For ITMS instruments utilizing external ion sources, such as laser desorption, trapping efficiency is known to depend on the phase and amplitude of the radio frequency (RF) pot
Investigations on ion injection into a laboratory-built quadrupole/ion trap tandem instrument (Nermag R10-10/ITMS Finnigan) with a 90ร geometry are described. The quadrupole dual electron impact/chemical ionization (EI/CI) source was used as an external source to prepare ions under EI (or CI) condit
