title: Potentiometric determination of certain alpha-aminohydroxy compounds by using an ammonia gas-sensing electrode.
abstract: A simple method is described for the determination of certain alpha-aminohydroxy compounds, based on the potentiometric measurement of ammonia released after oxidation with an excess of periodate. Ammonia is measured directly in the reaction mixture, with an ammonia gas-sensing electrode. Ethanolamine, diethanolamine, triethanolamine, serine, threonine, and glucosamine (0.3-6 mumole) can be determined with average errors of about 1-2%.
