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…
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…
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 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'm using chemstation revision G1701EA E.02.02.1431 and the last successful launch was a day yesterday. It seems the malfunction accrued (during a "run" with a "new" method we are trying. involves FID HS for DCM residue, all the vials were sampled…
