After most MSD maintenance (filament change/switch, source cleaning, etc...) I seem to have an issue with the baseline dropping in series (offset pattern) for up to 2 weeks afterwards. I'm new to this machine, but I'm in the process of slowly changing…
Hi, I am using a batch file to reprocess data under a different method. The integration and events table look correct on the screen. I have adjusted all of the batch settings options, but the final report only includes the sample information without any…
Hi there, I've recently started using a GCMS (7890A + 5975C MSD). The tune has failed and the GC shows a flat line at 0.5 whenever a sample is run. I've attached all relevant photographs I could think of, including the GC spectra where it all stopped…
I've recently been running into some problems with performing SureMass conversion of data collected on a 6546 LC-QTOF. I'm collecting both profile and centroid MS data using the default data storage thresholds.
Initially, I was running SureMass conversion…
Good morning, fellow colleagues. I have started to use MassHunter B.04.00 with my 6520B LC-QTOF. I am having some trouble setting up the diode-array detector on the HPLC from MassHunter. When loading in a HPLC method, the computer responds, Failed to…
Hello Nur5ik
Thank you for your question.
Disconnect or loosen the sample probe and rerun the "restriction and pressure decay test".
If you pass the first step, sample prove might be plugged. You need to change sample probe.
If the same step…
Hi Everyone,
Please can you help me. We have been having repeatability problems on the HP7890B for a long time and can't get to the bottom of it. Analysing for VOC. I have run lots of RSD measurements (10 injections). A common thing we are seeing…

Hello, I've been spending time getting my university's recently donated LCMS up and running, and I've been obtaining good results. This morning, however, the LCMS has been throwing errors every few minutes that's disrupting runs and ability to auto tune…
Well, I thank everyone for their help. I am learning, and so I set the DIP switches were pushed into 1,2,8 only high. Then restarted. It restarts and then fails. The problem is that the Lab Advisor is running via RS232 and it stops communicating because…
