WebQuadrupole Time-Of-Flight (QTOF) mass spectrometer is in B0-110. Background Tuning is the process of adjusting both the quadrupole (for Q-TOF) and TOF parameters to maximize signal intensity and maintain acceptable resolution, or to maximize resolution and maintain acceptable signal intensity. WebA brief introduction is presented to the basic principles and application of a quadrupole-time-of-flight (TOF) tandem mass spectrometer. The main features of reflecting TOF instruments with orthogonal injection of ions are discussed. for sale beachmere qld
