Interestingly enough, when running a method with a higher starting oven temperature, the abundance of the peak decreases until it pretty much disappears if the starting temperature is above ~175-200 degC. The peak also seems to be absent if I run while heating the oven, but keeping the inlet temperature off. So, thinking this might be an inlet issue, I then replaced the split vent trap, cleaned the inlet itself, as well as cleaned the vent line - also baked out the column some before re-installing. I am still seeing this contamination peak!
At this point, I feel I have replaced everything what am I missing? Anyone know what this peak could be characteristic of?
