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.
