Speed is Power.

Accurate mass analysis of sharp chromatographic peaks obtained by UFLC requires ultra-fast MS detection capabilities.
Greater speed. The LCMS-2020 offers UFswitching for rapid polarity switching between the positive and negative ionization modes
and UFscanning for ultra-fast scan measurements to capture the sharpest UFLC peaks.
Greater sensitivity.
