I´m working with a gc 8000 and I need to measure acetic but the gc doesn´t detect it.
I could measure it, but without a retention time constant: it goes from 4.8 to 5.2 minutes
I had a baseline ON, but when I measured this sample I needed to do another one and clean the system because there was a broad peak in 3 minutes. I had to do this, three other four times until I have a new constant baseline.
The injector is at 260, the detector is at 240; and the oven is at 170.
Could you tell me the retention time of the acetic in this conditions? Could you tell me the peak shape? Because I have one which is totally asimetric, and it looks like a a shoulder.
Other problem I have is the level loss, the flame goes out without any reason, because there´s H2 flow and it seems everything is stable.
