Sciex QTRAP 6500+ LC-MS/MS System

Sciex has launched its QTrap 6500+ LC-MS/MS system. The new system delivers enhanced selectivity, without compromising MRM sensitivity. The QTRAP scan function of MS3 adds an additional level of mass filtering and the SelexION +ion mobility technology which has increased the ion transmission twofold in addition to eliminating isobaric background interferences in complex assays.
