Hello,   I am not seeing all of the reference ions (negative or positive) while my qTOF instrument is in idle or acquisition.  Spectrum and Work List icons remain yellow whereas Vial icon remains red. A fresh reference solution was prepared, flow and function of nebulizer confirmed. Some additional details as follows:   In negative mode, seeing… (Show more)

Hi, After 3 weeks of the annual preventive maintenance, working well, the autotune is failing. We have vented and blown with helium in MS, but it is not resolved. Attached Autotune report. Thank you, Regards, Pedro

Hello:   We have a 6890 with a 5973 running MSD Chemstation (D.02.00.275) on XP and a 7890A with a 5975C running MSD Chemstation (E.02.00.493) on Win 7.   We need to upgrade our workstations to Win10.  Will either of the above work on Windows 10? If not, what is the path forward (i.e. we must upgrade the 6890/5973 to a newer model)?   Thanks,… (Show more)

Dear colleagues! Suddenly the new problem with our Agilent 7000A has appeared Instrument has worked quite intensively for a year in our laboratory (instrument has been bought refurbished 20 month ago). A month ago, during the analysis process, error 1.5 "Entrance lens driver cannot maintain the requested voltage" began to appear. After some… (Show more)

Hi everybody,   We have a GC 7890A with a 7000 triple quad MS. Lately we have cleaned the source as usual and we have obtained a not so good result with the autotune (counts for both analyzer and all ions five time lower than before the cleaning). The extractor lens wire (brown cable) was stuck between the end of the column and the source… (Show more)

Hi! I am a new member of the Agilent community. I have the following problem with the Agilent 7890A and 240 GC / MS system for several days: I can no longer activate any method in the dedicated software. If I want to change the active method, when I access the menu, the software shuts down. I can change the parameters of the active method but when… (Show more)

Hi! Recently we bought used Agilent 7000A triple-quad (7890A GC equipped with G7000B triple-quad detector). Several monthes ago we faced the problem with triple-quad detector that suddenly goes offline. MassHunter reported that connection was lost, ping from command line could not get a reply from detector (there is no problem with GC pinging).… (Show more)

Hello, The tune evaluation on the 5977B GC-MS is failing. The reason is 502/69 mass ratio is smaller than 2.4 (reading = 1.5-2.0), more specifically the 502 m/z count is around 7000-9000, instead of 20000 which is seen in previous autotunes. I cleaned the ion source, changed the filament and the next possible error that is showing is leaks or… (Show more)
