left it pumping over the weekend, 0.2ml/min, 50/50

came in yesterday and system full of air, not sure how as there was enough solvent
how can I fix this?

What is the solvent you are using? If this happens to me I ususally prime the system again and then push isopropanol through (higher viscosity - helps to push air through).

cheers, I tried methanol and that seemed to work

one thing I notice was that the filter was releasing air bubbles, took this off then no more air
