Variable Speed Dry Pumps for Mass Spectrometers

Atmospheric Ionization Systems with high flows, such as LC/MS/MS require enhanced sensitivity and optimal working pressure to match the mass spec inlet system. Agilent Technologies (formerly Varian) Inverter-driven pumps with unique, patented TriScroll design are multi-stage, dry vacuum pumps designed and manufactured for the highest reliability and durability. Pumping speed can be fine-tuned and adjusted to the nearest one Hz to deliver optimum working pressure and rotational speed can be adjusted. These features make it easy to match the pumping characteristics of your existing rotary vane pump and simplify system retrofit.
