Abstract: The method of converting nitrogen dioxide to nitric oxide which includes maintaining the nitrogen dioxide at a temperature from about 40*C to about 130*C. The nitrogen dioxide is exposed to ultraviolet radiation, whereby the nitrogen dioxide is converted to nitric oxide. A method of measuring nitrogen dioxide utilizing this conversion is also disclosed.

Abstract: A diffusion membrane material for a specific ion electrode which comprises a polymeric resin and a substantially water insoluble salt of the ion to be detected in admixture therewith. A method of making a diffusion membrane material for a specific ion electrode is also disclosed. The method comprises the steps of mixing a polymeric resin with a substantially insoluble salt of the ion to be detected. The resultant mixture is molded and sintered to provide a bar stock and the bar stock is formed into a diffusion membrane material.
