Request for help with Micromass Q-TOF
Posted: Mon Mar 08, 2021 3:10 pm
We bought a used Micromass QTof Ultima API. With standard, manual recommended settings we cannot observe any ion beam, we see only noise. The source and the readbacks look fine (as far as we can tell). We are trying to troubleshoot that and I have a very basic, naïve question:
Are the mass spectra we observe in the TUNE window from the electron multiplier detector, or they are from the Tof MCP detector. I cannot understand where the analog output of the electron multiplier goes, where it is digitized, how it is send to the EPC, and how can I observe the output of the two detectors separately.
I will highly appreciate if anybody can help us to figure those things out. Thanks!
