Intelligent Use of Retention Time During Multiple Reaction Monitoring for Faster and Extended Compound Screening with Higher Sensitivity and Better Reproducibility

11 Jul 2017

LC-MS/MS instruments operating in Multiple Reaction Monitoring (MRM) are widely used for targeted quantitation and screening on triple quadrupole and hybrid triple quadrupole linear ion trap (QTRAP® ) systems because of their well known selectivity and sensitivity. However, the current limit of a few hundred transitions per chromatographic run limits the number of analytes that can be monitored per injection. In this application note, find out how the new Scheduled MRM™ Algorithm offered in the Analyst® software version 1.5, only monitors the MRM transitions of the targeted analytes around the expected retention time.

QTRAP 6500+ system

SCIEX

The QTRAP 6500+ system featuring the multi-component IonDrive technology and enhanced with an IonDrive high energy detector+ pushes the boundaries of LC-MS/MS quantitation farther than ever before. The revolutionary sensitivity, speed, and performance delivered through these technology enhancements are designed so you can see it all, from low mass to high mass compounds, in positive or negative polarity – in a single injection, with high sensitivity, reliability, and confidence.
