Summary. The ‘glass’electrode technique and its application to environments likely to be encountered in food analysis is described. It is shown that the technique offers a rapid method of determining sodium concentration in the range 1 ppm to 2% in samples containing little or no protein. the ‘glass’electrode and flame photometer methods, as carried out with the types of instrument likely to be available in control laboratories, are shown to be of comparable accuracy. Results obtained with the two techniques agree to 1-3%. the ‘glass’electrode is shown to have certain advantages over the flame photometric technique, notably its freedom from interference by solid matter and chemical substances, resulting in simple and rapid sampling and calibrating procedures.
