ABSTRACT:
A ion selective electrode is formed by an electrode having a first membrane with a diffusion rate selective to heparin or other polyions, and a selective polymeric coating thereon having a polyion diffusion rate lower than the polyion diffusion rate of the first membrane. The electrode is sensitive to solutions containing low polyion concentrations such as low heparin concentrations.
