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.


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.
