Shimadzu LCMS-2020 Liquid Chromatography Mass Spectrometer is optimized for Prominence UFLC/UFLCXR Ultra Fast Liquid Chromatography. New technologies offer significantly improved scanning speed and positive-negative ion polarity switching time required for UFLC, while simultaneously increasing sensitivity.
LCMS-2020 combines the excellent compound selectivity characteristic of mass spectrometry with significantly increased overall productivity from method development to analysis. LCMS-2020 plays a useful role in a number of fields, including the synthesis of compounds in the pharmaceutical and chemical industries.
To detect both positive and negative ions, analysis is performed while switching between the positive and negative ionization modes. The LCMS-2020 Liquid Chromatography Mass Spectrometry adopts patented high-voltage power supply technology (Patent: US7855355) to achieve an ultra-fast polarity switching time of just 15 msec.
Superior sensitivity, repeatability, and linearity are achieved, thanks to the newly developed Qarray® optics.
In MS (mass spectrometer) scanning, a range of mass to charge ratios are determined in successive 0.1 m/z steps. This is controlled by applying a rapidly changing voltage to the quadrupole (quadrupole rods). By adopting Shimadzu's proprietary scanning technology (Patent: US8188426), high ion transmission is achieved without sacrificing sensitivity or resolution, even during high-speed scans up to 15,000 u/sec. Very narrow UFLC peaks can now be properly detected in scan mode acquisition.
