On Inert Extraction Source , What is the difference on instrument sensitivity when performing Atune vs Etune? On the Agilent Source Guide says that I can use either one but I noticed that if I perform an Atune the electron multiplier is 5times higher than when I perform an Etune, also the repeller energy is about 30 Time higher than on the Etune. Are the sensitivity for both tunes the same? Thanks in Advance
