Agilent 6560 Ion Mobility Q-TOF LC/MS

Categories:

Agilent 6560 Ion Mobility Quadrupole Time-of-Flight (IM-QTOF) LC/MS system with Agilent 1260/1290 frontend enables high-performance ion mobility and very precise collision cross section measurements without class dependent calibration standards. The innovative ion funnel technology in this instrument dramatically increases the ion sampling into the mass spectrometer and results in higher quality MS/MS spectra at trace levels.

* Signal-to-noise (S/N) ratio is not a valid measure of sensitivity, as the Agilent 6560 can separate the reserpine signal completely away from the background noise, creating an infinite S/N calculation. Reproducibility close to the limit of detection is a more appropriate measure.
