Ion Exchange

May 21, 2007 12:16 PM

I'm looking for a source for ion exchange resin membranes.

We used to use a product called AR-103, and anion exchange resin membrane for measuring plant nutrients in situ. (For our purposes they came in 6"x6" sheets, but it's not imperative at this point. We can trim down.) Unfortunately, our supplier has left the game and left us high and dry. I've done the "Contact Us" thing at the larger exchange resin people (Dowex, GE, Rohm & Haas) to no avail. Anyone have any insights or sources?

It's pretty clear from a brief Googling that a company named Dynambio in Madison, WI also supplies these, or used to. You can Google up their address pretty easily.

We use Rohm & Haas ion exchange media and membranes- I'm sure they will contact you if you persist; I've had terrible luck with many companies' websites contact forms.

Response by poster: Er, Dynambio was our supplier.

I'll keep poking R&H.
