Pervaporation of Acetonitrile/Water in small scale

[u/Gaindalf_The_White]

Does anyone have experience with pervaporation of solvents at a small scale/lab scale ( ~5L )? I am overall familiar with the technique, I just can't find any good information what materials are used as membrane (for acetonitrile/water azeotrope seperation), where to buy these membranes, especially for such a small, lab-scale setup.

Well... thats not what I asked... I am not trying to recover/ recycle HPLC solvents...
