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…
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…
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…
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, 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…
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…
We recently switched to MH 12.1 for our 6495C. This version of acquisition does not have tune context. Instead the autotune is in the TQ tab of the method.
When I request tune control, it does not change the TQ parameters. It only changes the temps…
The Signal-to-Noise function is better to work with printer, since there are more information on the print out than on screen, virtual printer will also do the job, When you started the function there will be guidance at the bottom of the window, it will…
We have a GCMS(5975C, intert EI source) which had been out of order since long 6 months due to ALS tray issue. After we installed tray, we cleaned ion source, replaced filaments, cleaned inlet, vent line and replaced split vent trap cartridge. Then tune…
