Hi all, recently we obtained a 6475 MS in our lab with an ESI and APCI source. The ESI source was no problem to set up, but the APCI source doesnt seem to get any signal. Not using APCI specific calibrant nor while simply scanning the spray coming from the LC system. except for this problem the system seems to be functioning perfectly, but I would really like to start using the APCI source as you could expect. Yes, the cables have been connected correctly, i dont see any warnings, faults popping up and the corona needle+ source have been properly cleaned. thanks for any suggestions!
Figo
