Mass Spectrometer Systems
Delivering the ultimate in measurement speed and sensitivity, the compact LCMS-2020
mass spectrometer offers faster measurements and higher detection sensitivity for
quicker and more accurate detection of trace impurities, environmental pollutants,
and other contaminants. When combined with a Prominence ultra-fast LC (UFLC/UFLCXR),
you’ll achieve the ultimate in separation performance and productivity.
High-speed polarity switching between positive/negative
Measuring unknown substances requires measuring in both positive and negative ion
modes. Since the positive ion/negative ion polarity switching speed of most LCMS
systems is slow, ultra-fast analysis required injecting samples twice for separate
measurements. UFswitching technology (patent pending) 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.
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 analyzer for substances most commonly measured
Fast scanning speeds
By adopting new technology (patent pending), a scanning speed of 15,000 u/sec is
achieved without sacrificing sensitivity or resolution, even during high-speed scans.
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.
Simply put, the new Shimadzu LCMS-2020 is the world’s most sensitive, fastest scanning
and fastest polarity switching quadrupole mass spectrometer available.
LCMSsolution 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
In addition, manual peak integration can be conducted on both LC and MS chromatograms
simultaneously, and a variety of formats are available for easier and more convenient
reporting. Learn more about LCMSsolution here
