The Micromass Quattro Ultima Pt is a high performance, bench-top, tandem-quadrupole mass spectrometer designed for routine LC-MS-MS operation. Quattro Ultima Pt may be coupled to: A HPLC system with, or without, an autosampler. An infusion pump. A syringe pump. Ionization takes place in the source at atmospheric pressure. These ions are sampled through a series of orifices and ion optics into the first quadrupole where they are filtered according to their mass to charge ratio (). The mass separated ions then pass into the ion tunnel collision cell, with axial field, where they either undergo Collision Induced Decomposition (CID), or pass unhindered to the second quadrupole. The fragment ions are then mass analyzed by the second quadrupole. Finally, the transmitted ions are detected by a conversion dynode, phosphor, and photomultiplier detection system. The output signal is amplified, digitized, and presented to the data system.
