Hi Lakshmi, Here is the reply from our compliance group.... Traceability and Audit Trails Data are generated by the same native chromatography data system (CDS) used in the daily operation of the instrument, which controls the system being qualified during…
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…
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?
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…
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…
#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…
This is a chromatogram of my high standard, Still haven't gotten to the low. Note that this is actually just one compound injected on the sorbent tube. The compound is methyl methacrylate. The tube is Carbopack B,X. The library identifies the compound…
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…
