It looks like theres a problem with the back inlet/back autosampler - the gc does not recognize it anymore - but it seems to be defined within the method, meaning it has a inlet temperature ect.
Did you change something regarding the back inlet? or…
Hi, I ran my batches with GC-FID under MassHunter Quant, but I cannot generate any reports. The error popped up during generating which is "Error: 'QuantDataProvider' object has no attribute 'FormatDateTime'." Has anybody faced with this issue to help…
After a failed methamphetamine quantitation, it was noticed that the methamphetamine peak shape on our GC/FID instruments has been consistently poor or deteriorating through out a run. This has been happening on both of our GC/FID instruments (all 3 columns…
Hi
Either there is leak or loop is not filling properly with sample for low area.
And for too hot transferline, may be PC board or sensor is malfunctioning or faulty of headspace.
You can change column or trim the column from inlet and detector…
Hello jeremy_lai ,
In your expressions you must check for both the existence of the qualifier and the outlier yourself. In the initial if and in the final one you need to add a check to see if there is a qualifier by checking to see if it is None. …
Hi everyone,
We are using a UV-VIS-NIR model Cary 5000. Recently when we validated the instrument. However, at the wavelength accuracy test using the Deuterium lamp, we found that 486 and 656.1 nm emission lines have been split into two emission lines…
Hi Brian,
What kind of detector are you using? From my experience with FID, you shouldn’t have issues with septa bleed from re-running samples within the same day. If you inject the vial and then re-run it after a day, you will probably see n-hydrocarbon…
Troubleshooting report generation in Chemstation. We have successfully generated 100s of reports using the report template and reprocessing when a run is disrupted. I have to sequences that have failed to run a report and I can't get it to via our usual…
While running oils and extracts on GC,the basline shows wandering as in the attached photo below in the range from 75 to 100 mins.The problem is not related to specific temperature because it appears at the beginning of the run,middle and at the end in…
