I have an Agilent 5975C MSD and 7890A GC that I'm getting a failed PING test on. I've done the troubleshooting I can (reboot system in proper order, reboot PC). I can ping the main IP but the ones going to the instruments fail. Please advise. PC is running…
I'm in IT support for a chemistry lab using an old Varian Cary Eclipse Fluorescence Spectrophotometer. The old PC the lab tech were using had some issues during Scan Setup where they were unable to input the necessary parameters for their measurements…
Hi, I am using Agilent 7820A GC-FID with EZChrom Elite data system. I am absolutely new to GC. Past few days I am trying to do a multi-level calibration for my analyte. But totally confused with the options I find in the software. So far I have done the…
"Instrument" software of our LC doesn´t show analysis results anymore. When we try to open result data, it shows the message "Incomplete results. 1 out 1 data files do not have a result file and will not show up on the report. To generate results recalculate…
Hi carcuri13, This sounds like the heater sensor assy is failing. If the change is rapid in temperature , the thermal block is not capable of changing quickly. The heater sensor would need to be replaced. Regards James
Thank you Paul. I was able to do all that now. I also did inlet maintenance:
opened the inlet completely, replaced guard column+fittings (ferrules on both ends, column nut to Ultimate union), gold seal+washer, and inlet reducing nut (used a better looking…
At some point I believe OpenLab CDS software, Rev. C.01.08 [210], was corrupted for one GC. We run two Agilent 7890B's on the software. There are two issues for GC-4, file path "\chem station\1\". The other GC \2\ is running perfectly. No issues at all…
A few things to check: - use the latest version of LabAdvisor (currently B.02.14 SP1) - thoroughly purge the entire pump with the selected solvent - double-check or replace the blank nut - using a piece of tissue, check all physical connections for leaks…
When we run standards (or ICAL) the internal standards get slightly higher the higher the concentration of the standard. The analyst has mentioned this with samples as well (dirty samples vs clean samples). When we run blanks or clean samples the IS goes…
I am having trouble separating methyl methacrylate (MMA) from another peak. The interfering compound, appearing in the front, is identified by library as 3,3-dimethyl-2-butanone and it is inherent to the sample. MMA appears as the split/tailing peak.…
