摘要
Screen-printed lactate sensors, with an outer membrane applied by an air-brush, were mounted in a how injection analyser. Diluted extracts of buttermilk and yoghurt were passed over the sensors. The lactate concentration in the extracts was determined with a high degree of accuracy and precision (based on variation among sensors). Fresh sensors were used for each new buttermilk or yoghurt sample, but individual sensors were capable of giving repeatable results, with standard lactate solutions, over a large number of injections.
