ABI 4000 QTrap
Description
The ABI 4000 QTrap is a hybrid QQQ/linear ion trap mass spectrometer which allows the array of scan types available in a QQQ setup to be exploited, with increased functionality obtained via linear ion trap mass analysis.
The system is particularly well suited to highly sensitive, targeted quantitative analyses of, for example, metabolites and complex peptide mixtures in multiple reaction monitoring (MRM) experiments. Other scan types include precursor ion scans and constant neutral loss scans, which provide highly specific means of monitoring given classes of analytes, for example classes of post-translational modifications.
