The XS Collision Cell from Waters Offers Increased Sensitivity and Resolution for Time-of-Flight Mass Spectrometry

Waters®’ Quadrupole Time-of-Flight (Q-Tof™) mass spectrometers are fast, sensitive, high resolution, accurate mass instruments that integrate fully with fast separation techniques and are capable of generating the information scientists need to detect, identify, and quantify trace level compounds in complex and difficult samples. This white paper reviews the XS Collision Cell as the latest technological advance that delivers increased sensitivity and allows the Q-Tof to match the quantitative performance of many tandem quadrupole instruments without compromising mass resolution. The segmented nature of the quadrupole rods of the XS Collision Cell allows a DC gradient to be applied in order to draw ions through the device rapidly and enables fast switching between multiple MS/MS experiments.
