Shimadzu Corporation Shimadzu Liquid Chromatograph Mass Spectrometer (LC-MS 2020) with a SPD-M20A Phote Diode Array Detector and a FCV-20AH Flow Control Valve Mass Spectrometer (MS)
UFswitching Technology
High-speed polarity switching between positive/negative ion modes
Measuring unknown substances requires measuring in both positive and negative ion modes. Since the positive/negative ion polarity switching speed of most LCMS systems is slow, ultra-fast analysis required injecting samples twice for separate measurements. UFswitching technology enables switching between positive and negative ion modes in 15 milliseconds so even the fastest LC peaks can be analyzed in both modes, thus increasing productivity.
UFsensitivity
Superior sensitivity, especially for ultra high-speed analysis
Innovative ion optics with the newly developed Qarray® ion optical system provide superior sensitivity, repeatability and linearity, achieving greater sensitivity than any other single quadrupole analyser for substances for substances most commonly measured.
UFscanning Technology
Fast scanning speeds
By adopting new technology, a scanning speed of 15 000 u/sec is achieved without sacrificing sensitivity resolution, even during high-speed scans.
Easy Operation/Maintenance
The ESI method typically used for LCMS can be replaced with APCI, which is suitable for less polar compounds, or with a dual ionization source (DUIS) for simultaneous operation of both ionization modes, quickly and without tools. Selection of the DUIS ionization mode (ESI or APCI) can be performed via the computer. In addition, the desolvation line, where the ions enter the MS unit, can be replaced without breaking the vacuum.
Software
LCMS solution includes an improved data browser function to help qualitative processing of multiple sets of data. This data browser allows comparing multiple sets of data or confirming impurities by linking to LC or MS data, which is especially helpful for users in fields where compounds are synthesized, such as pharmaceuticals and chemical products.
