蛋黄中盐度检测方案(自动电位滴定)

蛋黄中盐度(氯化钠)的测定 应用资料通常，氯化钠是根据摩尔法测量的。搅拌蛋黄后，用纯水稀释，再次搅拌。样品在自动电位滴定仪上用0.1mol/L硝酸银滴定至终点。通过将滴定体积转换为氯化钠来获得盐度。终点位于最大拐点。TIF-01045enLK-M KYOTO ELECTRONICSMANUFACTURING CO.，LTD.1/1 Application MemoSalinity of Egg Yolk Industry Food & beverage Instrument Automatic potentiometric titrator Measurement method Precipitation titration Standards GB/T 12457 1.Overview Generally， sodium chloride is measured according to Mohr method. After stirring the egg yolk， dilute it with pure water and stir again. The sample is titrated by anautomatic potentiometric titrator with 0.1mol/L silver nitrate up to the endpoint. The salinity isobtained by converting the titrated volume to NaCl. The endpoint is found at the maximumpoint of inflection. 2.
