When we came back to the lab, it showed the following faults: 5.31 Main board #1 shutdown 7.5 Filament drive timeout 7.30 Main board #2 internal shutdown 7.31 Ma... I made the mistake of doing a standard tune multiple times instead of an auto-tune and I know this lowers the sensitivity according to the hardware manual. Could this be the source? If so, how can I fix it? My lab recently changed the filaments and installed a new electron multiplier on our Agilent 5975C. When I try to tune the peaks all seem like noise and then if gives me an error for the tune reading " Tune action Sto... I am trying to do an initial tune with our 6520A after I vented the instrument. Error occured while it was optimizing for Quad AMU and the error message is "No valid optimum found in ramp (abundances were all too low)... After most MSD maintenance (filament change/switch, source cleaning, etc...) I seem to have an issue with the baseline dropping in series (offset pattern) for up to 2 weeks afterwards. I'm new to this machine, b... Hi, I have a question. I loose the sensitivity of C35-C40 standards. I usually inject a standard mix (C21-C40) but over the time I loose the high chain length carbons. Either I see very little peaks or I see n... ms #g1956 electronics signal loss chem station #error log files Hello everyone!We have a Lc MSD VL G1956A single quad.

Hi, I have HP 6890 Plus GC with 5973N MSD system and using MSD Productivity Chemstation E.02.02.1431 (G1701EA) Software. As using this software faced a question regarding Reports.

And if not, are the intensity values of each mass averaged over a time window? Recently, after a pump down and HV conditioning sequence, TOF electronics shut off without any obvious error. Seems to have been software related, but I don't want to keep attempting to condition the electronics in or... Where can I plug in my serial number for my 6460 LC/MS to see the manufacture date? Thanks to Gerry Alexis. Agilent QqQ RSS. This document also includes SQ shutdown. Attached is a shut down procedure for Agilent 6100 series LCMS. Thanks to Agilent OTS Engineer Howard Sanford. I keep getting this error on my 6100 LC/MS. Any help please?
