Shimadzu LCMS-2010A Single Quadrupole Mass Spectrometer ( LCMS2010A 2010A 2010 A Liquid Chromatograph ) The 2010A ESI machine is particularly useful for the analysis of metabolites, co factors, peptides and smaller proteins, up to a mass of about 40.000 DA. The instrument has also proven useful for monitoring HPLC effluents (LCMS) and in quality control on the integrity of precious nucleotides and neuroactive pharmaceuticals (for the Department of Molecular Neurobiology). • Fast scanning electronics support 6000 amu/second (6000 data points per second) acquisition rates for fast chromatography applications. Peak widths of several seconds may be detected using fast scan rates to maintain spectrum quality without affecting the accuracy and precision of detection. • Unique Q-array ion guide. Q-array ion guide configuration is unique - three quadrupoles with different inscribed radii coupled with an octapole. The Q-array precisely focuses ion delivery into the mass analyzer. The ion optic design for the LCMS-2010A is the most innovative design in ion focusing technology. Using the Q-array and octapole RF guides to precisely focus ions to the mass analyzer, we deliver new limits of detection for LC.
