Agilent Technologies has introduced an ion trap mass spectrometer that is claimed to be approximately 10 times more sensitive than its predecessor. The increased sensitivity, resolution and scan speed of the Agilent 1100 Series LC/MSD Trap XCT promise improved performance for many applications such as the identification and characterisation of biologically significant, low-abundance proteins for disease research.
A limitation on the performance of any quadrupole ion trap mass spectrometer is trap capacity. Careful changes to trap materials and geometry and new scanning alarms for Agilent's non-linear ion trap have improved trap capacity by four to eight times. This increase in trap capacity translates directly into increased sensitivity. The improved ion trap and new scanning algorithms also improve mass resolution and scan speed.
