Hello mkaadan ,
What I meant by a "low" failure rate (notice the quotation marks), is that it is likely not an indication of a leak, as that would result in a lot more samples failing, or potentially all of them. By no means I wanted to minimize the…
Can SimDis data processing be performed manually (i.e. without the aid of additional SimDis software produced by Agilent or a third-party) with a GC running Chemstation?
I'm looking for a low-cost solution to perform SimDis analysis of jet-fuel samples…
Hi guys, I'm experiencing regular times ghost peaks starting at 120°C to 295°C.....my setup is GC-FID 6890, Low pressure drop, Ultra Inert Liner with glass wool, column HP1 widebore..... I have cutted the inj/det 5 inches of column, heated at 295°C with…
HI Lars,
Yes, you can run the test on a VI. Specific to your system, a failing result could indicate a leak within the inlet or at any of the in-line connections of your GSV, so the results may not be clear without a point leak detector. I would also…
I’m sorry for the delayed reply to your message. Do you still need assistance with this? If you do, please take into consideration the notes below. However, if the issue was resolved, could you please share what the resolution was?
From what I understand…
Disconnect the sample probe from the valve and start the leak and restriction test. If it passes this step, it means that there is some restriction in the sample probe, enough to cause that part of the test to fail. Try a brand new probe. If it fails…
Hello, H2 is the fuel for the flame in the FID, so if you are out of H2 then the FID will not be able to light. That is very likely the reason why you are not seeing a signal from the FID.
I have decades of experience with consumer products, all on Agilent GC, GCMS, and HPLC.
If I was needing to quantitate 1,2-octanediol in cosmetics samples, I'd extract the sample with dimethylformamide and add BSTFA to make trimethylsilyl derivative…
No, the flows on the two columns downstream of the switch have to be equal. They are feed by the same pressure source, so since MSD is under vacuum and the FID is ambient, the column connected to the MSD has to have more restriction, to keep the flows…
