Valve change causing large ramp in chromatgram
Posted: Mon Feb 10, 2014 6:45 am
With our GC TCD signal we have a valve change at 4.0 rt. When the valve changes we get a large ramp in the signal. Is there a way of removing this ramp?
Too little info.
Pressure difference ? TCD is flow dependent. Ramp ?? Column bleed when second column broght into line ?
