The AB/Sciex 4000 Qtrap is a triple quadruple (QQQ) instrument, specialized in selected reaction monitors (SRM)/multiple reaction monitor (MRM) for absolute quantification of molecule(s) in a complex ...

MRM 3 increases the specificity of SRM detection by using resonant excitation to fragment primary product ions trapped in the Q3 linear ion trap. The detector eventually scans the secondary ...
