agreed - though experience forces me to glower preferentially at the water.DR, I see what you're saying, but I would argue that the information is consistent with contamination in the A solvent (not necessarily in the aqueous part of the A solvent). I can easily imagine a non-polar contaminant in the ACN which would be totally retained at 30% and elute at, say, 50%; in other words, I don't think we can exonerate the ACN.
Either way, though, the Empore filtration is woth a shot.
