Used WATERS / MICROMASS Q-TOF II #9395446 for sale

WATERS / MICROMASS Q-TOF II is an analytical spectrometer used to determine the mass-to-charge ratio (m/z) of ions in a gas phase. It is a multi-quadrupole, time-of-flight (TOF) mass spectrometer designed to provide accurate mass small molecule and peptide analysis. The instrument utilises a quadrupole/time-of-flight (QTOF) hybrid mass analyser, which combines the initial separation capabilities of a quadrupole mass analyser with the high resolution provided by a TOF analyser. WATERS Q-TOF II consists of the ion source, the quadrupole, and the TOF analyzer. The ion source of MICROMASS Q-TOF II is capable of producing multiple types of ions, including positive ions through electrospray ionisation and negative ion chemical ionisation. The ions are then sent through a quadrupole, which is used to filter out unwanted ions based on their m/z values. The remaining ions are then passed through the TOF, which works by measuring the differences in flight time of the ions as they travel down a long flight path. The TOF then calculates the m/z of the ions and rapidly transmits the data to a computer. Q-TOF II is capable of measuring ions with m/z values ranging from 1 to 2000. It provides high-resolution data by accurately measuring m/z values up to 0.0001 Da, and measuring low-mass molecules and peptides with improved signal-to-noise ratio. In addition, it utilises an Electrodynamic Ion Funnel (EDIF) technology for increased sensitivity. Overall, WATERS / MICROMASS Q-TOF II is a versatile and reliable mass spectrometer capable of providing accurate m/z measurements. Its combination of quadrupole and TOF analysers facilitate high-resolution and sensitivity, which makes it an excellent tool for the analysis of small molecules and peptides.
