Liquid Chromatography Tandem Mass Spectrometry with Ion Mobility
Dionex - ABSciex
Ultimate 3000 UHPLC Qtrap 5500 with Selexion Source

The Qtrap5500 LC/MS/MS system (AB SCIEX) is designed to excel at detection and confirmation of low-level analytes, and can be specifically used for quantification, verification and validation of  protein/peptide biomarkers. The QTRAP® 5500 system houses a linear ion trap with ultra-fast scan speeds of up to 20,000 Da/s. The flexibility of this system allows a variety of acquisitionmodes, including high-sensitivity full-scan MS, MS/MS, and MS3 capabilities. High-selectivity can be achieved from true triple quadrupole precursor ion (PI) and neutral loss (NL) scans. Accurate and precise quantitation can be obtained by selected reaction monitoring (SRM, also known as Multiple Reaction Monitoring, MRM) using the high-sensitivity triple quadrupole configuration. Furthermore, the QTRAP 5500 is equipped with a differential ion mobility source. This novel SelexION™ Technology device delivers a new dimension of selectivity and performance for applications requiring the separation of isobaric species, elimination of challenging co-eluting contaminants and reduction of high background noise.
