Quadrupole Mass Spectrometers

Quadrupole Mass Spectrometers A quadrupole mass spectrometer contains four parallel cylindrical rods which can scan or filter sample ions based on their mass-to-charge ratio. Opposing rods are connected electrically and a radio frequency voltage is applied between the pairs of rods. Ions travel between the rods and only ions with a specific mass-to-charge ratio will exit the quadrupole; other ions will collide with the rods. The desired mass-to-charge ratio can be altered by changing the applied voltage. Triple quadrupole mass spectrometry makes use of the same technology, but uses a linear series of three quadrupoles to improve sensitivity and selectivity. This type of spectrometry is useful when studying particular ions of interest since it is able to stay tuned to a single ion for extended periods of time.

Xevo TQ-S micro

Xevo TQ-S micro

Waters Corporation

  • Catalog Number: 720005046en
  • Description: Overview: The Xevo TQ-S micro incorporates revolutionary design to produce a tandem quadrupole instrument with a small footprint that delivers consistent low levels of quantitation with a wide dynamic range. Robust performance begins in the source with ZSpray geometry, efficiently removing neutral molecules while drawing the ions through the sample cone into the analyzer. The StepWave ion guide in the Xevo TQ-S micro is designed to cope with the challenges in the modern laboratory that are produced by high sample throughput and difficult matrices. Neutrals and gas load are passively removed for enhanced transmission with the ions actively transferred into the mass analyzer, improving sensitivity and robustness. All this is achieved while maintaining an extremely small footprint due to the class-leading compact design of the Xevo TQ-S micro.

    Features
    • Robust performance enabling reproducible detection of analytes at low levels in complex matrices
    • Confidently quantify more analytes using high acquisition rates
    • Accessible sensitivity and method transfer with the Xtended Dynamic Range (XDR) detector
    • Understand sample complexity and improve method development with RADAR
  • Mass Analyzer: Two High-Resolution, High-Stability Quadrupole Analysers (MS1/MS2)
  • Resolution: Automatically adjusted (IntelliStart) to desired resolution; (0.50 Da, 0.75 Da or 1.00 Da FWHM)
  • Mass Range: 2 to 2,048 m/z
  • Scanning Speed: Up to 20,000 Da/s
  • Dimensions: Width: 35.6 cm (14.0 in) Height: 60.0 cm (23.6 in) Depth: 93 cm (36.6 in)
