Mass Spectrometry Advances with Vacuum Technology
An interview with Richard Stern, Ph.D., Managing Director, CCIM (SIMS facility) University of Alberta
Q: What is the important role of vacuum in the instrumentation?
A: "We have an instrument called an ion microbe probe, which uses the analytical technique called secondary ion mass spectrometry. As for most mass spectrometry, it operates in a vacuum environment to avoid the ions colliding with molecules in the atmosphere, and therefore degrading the performance of the instrument. And so, vacuum is a prerequisite for mass spectrometry."
"We want to avoid particulates and oils that potentially could back stream into the vacuum environment, so there's a great appeal in going with an oil free pump to avoid the possibility of contamination of your vacuum by hydrocarbons in the oils.”
