Turning off the systems on Friday night that need to be ready to go on Monday morning is not recommended. It can take quite some time for a GC/MS to come back up to operational after being shut down. Even cooling the temperatures all down and then heating…
Wondering if anyone has experience detecting acetic acid and formic acid using GC-FID HSS. I am trying to develop a method based on the limits described in USP <467> of 5000 ug/mL of each of the two solvents, but having a hard time seeing any peaks.
I have a gas-phase reactor system that uses the FID of a 7980A to analyze the product mixture. Currently, I have a pressure buildup (up to 30 psi - the carrier gas delivery pressure) when the system is stationary. When the gas sampling valve actuates…
Good morning,
We have an autosampler (Agilent G4567A) for our GC-FID (7820A) and the following method for cleaning and injecting samples.
I have noticed that when the syringe pumps 2µL of sample for cleaning, it then pumps quite a large volume of…
Hi,
After a power cut, the batch file I had open on my desktop seems to have become damaged...
On opening the batch, it fails to open... small dialogue pops up >> "failed to open quick scan file. Failed to read binary quick scan file."
Has anyone…
hi community we are developing a method on short chain fatty acids in plasma sample, using a DB fatwax UI column on GC-FID. we are using diethyl ether as extraction solvent however our recovery of patient samples are not so good and looking to use Isoproponol…
I have a 6890N GC with an MSD and a GC that I am trying to qualify. The MSD works fine but when it comes to the FID the units are showing as mAU and not PA so it will not pass the validation test. Does anyone have any idea on how we can change the units…
Hi, I know this is an old thread, but I am having a very similar issue. I am wondering how did you know to replace the interconnect spring rod? How did you know this was the issue, and that it was not instead an issue with the FID board or the electrometer…
I have a 6890N GC with dual FID. The back column has a much higher flow rate than the front column. The two columns are identical and the setup for inlet, column and detector are identical. I have also swapped the EPC's between the two detectors. Seems…
