Not recommended vacuum pump.
Application Area: Targeted metabolomics
"I totally agree with the previous review: I would not recommend this system to anyone and it is unbelievable that MS vendors still sell any systems with these pumps. Unfortunately, Sciex delievered our 2 QTRAP6500+ systems with two of these pumps each. We already had to replace one after just 1 year of use, another one needs to be replaced in the next few weeks as it constantly leaks even after maintanence - after 2.5 years of usage. Anyone willing to buy a new MS system should insist on not receiving this pump with the new system."

High possibility for oil leakage
Application Area:ICPMS Agilent 7900
"This pump has a high tendency to leak oil and is not an environmentally friendly pump. Best to be used in a controlled environment (AC) or Cabinet. I would not recommend this costly vacuum pump, unless no choice."
Manufacturer's ResponseThe MS 40+ was designed specifically to support LCMS and ICPMS instruments. Early experience did show some instances of oil leakage when operating in challenging environments, and subsequent technical improvements address this concern. While dry pump options cost about four times as much, the MS 40+ single stage pump does represent a cost-effective, environmentally friendly alternative. MS 40+ uses less oil than dual-stage oil-sealed alternatives and employs a frequency inverter to reduce power consumption. A quiet cover solution is available to greatly reduce ambient noise.
The MS40+ is the roughing (foreline) pump of choice for LC/MS and ICP-MS instruments. The MS40+ single-stage, oil-sealed rotary vane pump that provides a high pumping speed in a pump with reduced dimensions is equipped with an integral exhaust /oil filtration system featuring replaceable exhaust filter elements. This makes this pump suitable for high gas-throughput conditions, and providing a base pressure of < 5-2 mbar.
