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…
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…
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…
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…
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…
#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…
We work with a Q-TOF 6545 and it fails positive auto tune. Is there anyone who knows this error, what causes it and what can be done to rectify this? Thank you
Hello everyone,

We get a TIC…
Hello, I am trying to generate a streamlined intelligent report in OpenLab where we can capture all peaks of our SEC gel filtration standard in a single table and be able to evaluate APD Pass/Fail for each peak and Resolution between BGG and Ovalbumin…
