AB Sciex API 4000 QTRAP

A high-performance ion trap and a high sensitivity triple quad, all in one system.

The innovative AB-SCIEX 4000 QTRAP Linear Ion Trap (LIT) technology combines fast, sensitive qualitative analysis with proven, high-sensitivity quantitation of the industry-standard triple quadrupole.

SCIEX linear ion trap (LIT) technology enables unmatched quantitative and qualitative performance within a single LC-MS/MS system. It’s use of a quadrupole mass spectrometer as a linear ion trap significantly enhances ion trap performance by increasing ion capacity, improving injection and trapping efficiencies, and increasing duty cycle.

The 4000 Q TRAP mass spec system provides true triple quadrupole multiple reaction monitoring (MRM) at the highest level of sensitivity, as well as extended dynamic range, ensuring superior quantitation performance for both small molecules and peptides. The highest sensitivity neutral loss and precursor ion scans and enhanced multiply charged scan can be used in flexible combinations to enable information-rich, high throughput workflows. Automated LC/MS/MS workflows using Information Dependent Acquisition (IDA) provide the framework for deriving maximum information from every experiment. When used with the 4000 Q TRAP system’s powerful mixed scan modes, IDA lets you focus on specific ions of interest for increased productivity.

With its outstanding quantitative sensitivity and qualitative performance, the new 4000 QTRAP LC/MS/MS System opens up a new class of application workflows for proteomics, drug discovery, and drug development. By combining true triple quadrupole scan modes with sensitive ion trap scans in a single LC/MS/MS run, you can achieve results that previously required multiple analyses on multiple MS platforms. In many cases, you can acquire data that is difficult to obtain by any other means.
