Varian 240-MS Ion Trap Mass Spectrometer 1440 VA with N2 Vent Made in USA

Description: Varian 240-MS Ion Trap Mass Spectrometer, 1440 VA w/ N2 Vent - Made in USA An ion trap mass spectrometer functions both as a mass spectrometer of considerable mass range and variable mass resolution and as an ion store in which gaseous ions can be confined. Unlike other mass spectrometers that operate at pressures <10^−6 Torr, the ion trap operates at 1 mTorr of helium. As a storage device, the ion trap acts as an ‘electric-field test-tube’ for the confinement of gaseous ions either positively charged or negatively charged. The confining capacity of the ion trap arises from a trapping potential well formed when appropriate potentials are applied to the ion trap electrodes. The ion trap functions as a mass spectrometer when the trapping field is changed, so that the trajectories of simultaneously trapped ions of consecutive specific mass/charge ratio become sequentially unstable, and ions leave the trapping field in order of mass/charge ratio. Upon ejection from the ion trap, ions strike a detector and provide an output signal. Varian 240-MS Provides:Unsurpassed sensitivity (200 femtogram OFN)Less maintenance and high reliability to deliver maximum productivityAccurate identification and quantification of trace analytesA unique choice of configurations with internal and/or external ionizationIntuitive software that makes operation simplePowerful MS/MS and CI options The 240-MS offers a range of advanced ionization and scanning techniques to enhance selectivity and limits of detection. MS/MS and MSn reduce matrix influences and provide more detailed structural information. Take advantage of positive or negative chemical ionization for compound confirmation and enhanced selectivity.
