UHPLC Quality - Speed is Power.

High-speed HPLC analysis to improve lab analysis productivity began in 1982 with the Shimadzu LC-5A/FLC column. In 2006, the Prominence UFLC/XR column system achieved ultra high-speeds while ensuring repeatability during continuous multi-sample analysis, in addition to maintaining durability and other forms of data stability.

Since general HPLC analysis is insufficient with respect to qualitative capabilities, risks related to overlooking impurities that can obscure peaks remain. Mass spectrometers are effective at minimizing these risks. To date, however, a commercial MS capable of reliably providing the kind of sharp peaks obtained with ultra high-speed LC has not been available.

Now, an ultra high-speed MS, compatible for the first time with ultra high-speed LC, has been released

The ultra high-speed LC/MS Prominence UFLC+LCMS-2020 improves the speed and reliability of HPLC analysis, offering dramatic improvements in lab productivity.

3 points yielding ultra high-speed, ultra high-sensitivity MS measurements

By incorporating the following innovative features into the LCMS-2020, the sharp peaks of ultra high-speed LC won't be missed:

  • UFswitching (high-speed positive/negative ionization mode switching)
  • UFscanning (high-speed scan measurements)
  • UFsensitivity (superior sensitivity and repeatability thanks to newly developed ion optics)

High-speed polarity switching between positive/negative ion modes

To detect both positive ions and negative ions, measurements are performed while switching alternately between positive and negative ionization modes. With the LCMS-2020, ultra high-speed polarity switching is achieved by adopting a high voltage power source loaded with groundbreaking technology (patent pending).

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

The scanning speed depends on the m/z ratio. This is controlled by applying a voltage to the quadrupole (quadrupole rod). By adopting new technology (patent pending), high ion permeability is achieved without sacrificing sensitivity or resolution, even during high-speed scans.
