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…
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…
Hi mazarakis, I do not see an advanced operation manual published as of yet. I have attached the 8890 Operation Manual in case this helps. Regards James
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…
Hi Ron, cheers for that. I have made a note of that method flow, thanks, but it's looking like it may be a touch moot; I cannot find the discs anywhere. I have sent an email to our IT team to see if they have them, but otherwise I'm at a bit of a loss…
Resurrected a 6890 which has not been used for a while. When the chemstation is turned on, it gives message of "Limits fail: liner(injection)". Pulled out and cleaned/replaced microseal (fine), glass liner with o-ring (no physical samage) and golden seal…
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…
Thanks ryoboyle and dheyaaldeen . I renamed the 4 files (config.reg, ChemStationPerInstrumentSettings.config, instrument.config, RapidControl.InstrumentConfig.xml). I do not have a user.mac file in the CORE folder. The program opened once and I reconnected…
Hi Nick- Thanks for that information! I'm not sure if that's the cause here. It was 8 million when it was installed in December 2015, in August 2016 it was 9 million, March 2017 it was 8 million, April 2017 was 7 million, then August 2017 it was only…
