Facility/Equipment Details
Description
Shimadzu's single quadrupole mass spectrometer capable of resolutions into the parts per billion (ppb) range. With ultra high speed switching, scanning, and sensitivity, combined with Dual Ionization Source (DUIS).
To detect both positive ions and negative ions, measurements are performed while switching alternately between positive and negative ionization modes. The LCMS-2020 achieves ultra-high-speed polarity switching by adopting a high-voltage power source loaded with groundbreaking technology. This fast switching occurs in only 15 msec – the industry’s fastest switching rate for a single quadrupole mass spectrometer to date.
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 new technology developed by Shimadzu, 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.
DUIS enables ESI, APCI, Positive, or Negative Ionization All at the Same Time… Significantly Improves the Efficiency of Analyzing a Wide Variety of Compounds at the Same Time or Analyzing Unknown Compounds
