Hydrogen/deuterium exchange reactions of protonated and sodium cationized peptide molecules have been studied in the gas phase with a MALDI / quadrupole ion trap mass spectrometer. Unit-mass selected precursor ions were allowed to react with deuterated ammonia introduced into the trap cell by a puls

The reaction chemistry between dimethyl ether (DME) cations and polycyclic aromatic hydrocarbons (PAHs) was elucidated by isolating three different types of DME ions using a quadrupole ion trap and reacting them individually with neutral PAH molecules eluting from a gas chromatographic column. The r
The collision-induced dissociation, (CID) mass spectra of 11 common s-triazine herbicides were investigated using gas chromatography/tandem mass spectrometry on an ion trap mass spectrometer with a temperatureprogrammable injector. The precursor ions of the CID mass spectra studied included both the
De novo peptide sequencing in an ion trap mass spectrometer coupled on-line with a capillary HPLC using 18O labeling provides a viable alternative to the method using the combination of nanospray, 18 O labeling and a quadrupole/time-of-flight mass spectrometer.

## Mass -selected reagent ion chemical ionization (CI) performed in an ion trap instrument is an efficient tool to investigate gas-phase ion reactivities and therefore to find out new and/or optimized applications for structural analysis. For instance, it was shown that the C 3 H 6 O + . (58 mass
A searchable library of MS/MS spectra obtained using a quadrupole ion trap mass spectrometer and electrospray or atmospheric pressure chemical ionization is presented. The application of wideband excitation (activation) and normalized collision energy leads to highly reproducible mass spectra which
