Compound Identification Procedures Combined with Quick-CI

The Quick-CI function is enable easy and simple use of the EI and PCI (Positive ion chemical ionization) mode using an NCI ion source without venting the MS. PCI can be obtained as a simple method of confirming molecular weight by molecule protonation and the combination of EI and PCI is a powerful identification technique when a compound cannot be identified based on its EI mass spectrum alone. Also, since the selected ionization mode is saved in a method file, the user can switch between EI and PCI for consecutive analyses.
This Application Data Sheet presents a compound identification performed by combining the mass spectrum information obtained by the EI and the PCI using an NCI ion source.
