Dear Bill Melchior,
I think you got the recipe for "Aqua Bidest" (correct: Aqua bi destillata).
Since some years I avoid "Aqua Bidest" because it contains more organic
traces (due to the destillation). If you use a UV-Monitor at 180 to 220 nm
in your HPLC system this may cause problems. We found that "Aqua Demin"
(deminralized water) works better.
