#I am currently battling with MH 4.5 and a generic communication error that has cascaded into me not being able to bring the 7700x into “shutdown” mode for ~6 weeks now. I have had numerous calls with tech support and all suggestions have failed to this…
Hi,
Every time we vent and vacuum down the MS2 auto tune fails with the high mass.
I've tried to tune from factory settings and manual tune using a file that was used prior to the shutdown.
The instrument is second hand so we have had the vendor…
Hi, I would be grateful for the community's insight on an issue that has been plaguing our 6520 Accurate-Mass QTOF-LC/MS. We are able to successful turn on the instrument, power condition, do mass calibrations, and TOF tunes (all the way from quick tunes…
I did a lens ramp on the failed BFB_AT and the emission ramp for 50 amu was very choppy. Setting the emission at 50 amu is where the tune process fails. Could this be due to a hardware problem?

Hello tdnola , "in use by another..." is a safety function that prevents a second session to the MSD: OK & wanted function. 1st) troubleshooting because a PING does only a small (OSI) communication check (are voltages & cabling OK?), I recommend the communication…
Hi community,
maybe someone has an idea what I could do, before a technician comes over.
During my absence my colleagues told me that our HPLC (1260 Vialsampler, 1260 Inf II Flex pump, TCC, FC-AS, DAD) does show a peak shift of about 3 to 10 minutes…
Hello Yanding, Glad to hear that worked! The needle to seat connection is very resilient to pressure, and can hold at 600 bar and more. I do not believe that would be the reason why the connection failed, it is most likely that the screw or other part…
Use 1 meter of deactivated fused silica tubing going into the source (the same diameter of your column), then use a union (either the press-fit glass type of, better yet, the SilTite brand) to connect to your column in the oven. When you want to change…
