We just bought a mass-spec and all the vacuum gear. I think I need a lie down in the dark now.
What do you think of my obtaining the Extorr XT100 Residual Gas Analyzer which would provide me with a Pirani vacuum gauge for lower vacuum values and a Bayard-Alpert gauge for the higher vacuum levels. In addition, I get a spectrum analyzer that goes from 1 to 100 amu. That would allow me to see the H2O peak at 18 and the He peak for detecting leaks and also later on, detecting He if the reactor produces any.
