Subject: RE: [DCHAS-L] Procuring Acetonitrile
We started capturing our waste and distilling it several years ago as
a cost savings so we have inadvertently protected ourselves at least a
little. We use a simple benchtop still (located in a hood). You need
to account for the water content. (84% acetonitrile, 16% water)
Also, depending on your sensitivity needs, you can simply re-use the
waste. That causes a baseline shift, of course, but you can sometimes
deal with that for a short while.
Good luck!
