LCMS-2020 - Features
High-Performance [Liquid Chromatograph Mass Spectrometer
High-speed polarity switching between positive/negative ion modes
To detect both positive and negative ions, analysis is performed while switching between the positive and negative ionization modes. The LCMS-2020 adopts patented high-voltage power supply technology (Patent: US7855355) to achieve an ultra-fast polarity switching time of just 15 msec.
Superior sensitivity, especially for ultra high-speed analysis
Superior sensitivity, repeatability, and linearity are achieved, thanks to the newly developed Qarray® optics.
Fast scanning speeds
In MS 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.
