The Agilent 6545 LC/Q-TOF is the standard for mid-range quadrupole time-of-flight LC/MS performance. Designed for untargeted sample analysis, it enables broad screening, comprehensive profiling, and identification of unknowns. The 6545 LC/Q-TOF MS delivers sensitivity, resolution, mass accuracy, isotopic fidelity, and speed in one measurement.

With LC-QToF-MS, better signal to noise ratios should be obtained although the ion collection of the quadrupole ﬁlter does not have a 100% efﬁciency and some ions are lost, resulting in a sensitivity similar to or worse than LC-ToF-MS. Nevertheless, sensitivity is a parameter that changes a lot depending on the
