I have proposed system from agilent 7890B to check high purity gases . system consists of TCD , PDHID and FID . me question is do you think that system is complicated and i have risk that if any fault happened the whole system will be down . How to guard…
Hi Carmen,
Visually check your column in signs of contamination of stationary phase. It looks like your column was too old. In that case you could just reverse the column direction, and put for for long term conditioning at room temperature, then condition…
Hi Kris, thank you! I tried to upload the screenshot of the version info, but I failed. So I have to type all of them out since I'm not sure which one is useful. Hope it can help!

Hello,
upon start vacuum sequence. You should hear a clik. This is for BK. Monitor IF/BK meter at that point. it has to go lower than 20 Pa. Then you should hear a second click. This time another valve open. It should rise above 20 Pa. Then after…
Hi All, I'm trying to get the following expression to work in a Qual 10 report (in excel format as that's about the extent of my coding knowledge): =IF(Area<DB_Notes,"Fail","Pass") to flag compounds which are less than a defined minimum peak area (which…
What should you consider when selecting gases for your new GC or GC/MS system?
Which gases will you be using?
Did you c onfirm that gases available are a supported configuration for installation ?
Gas requirements are specified in Site Preparation…
Hi kalle-h,
Has the method worked well for you in the past? Any changes recently like column trims? Sometimes small pieces of column can get caught inside the modulator fittings and impede flow, which has negative effects on our data.
If your peaks…
Dear Community
I am using a GC/FID from Agilent with Openlab CDS. The GC/FID has to columns (front and back) which gives a slightly different retention time for the same substance. I use both lines, one for the measurement and the other for the control…
