The pH meter is calibrated using standard buffer solutions with known pH values to ensure accuracy. The pH value is then calculated based on the Nernst equation using the EMF measurement. This method is widely used in various industries and laboratories for the accurate determination of pH value ...
pH determinationpH meterIodoacetate methodMeat qualityIn scientific meat quality studies, pH values are usually determined either electrochemically with a pH meter or using the iodoacetate method. As only few studies have been published that directly compared both methods, in the p...
The acid-alkali titration method of determination of degree of substitution(DS) for starch acetates has been improved by using acetone as solvent instead of ethanol. 测定醋酸酯淀粉取代度 (DegreeofSubstitution ,简称DS)的方法通常有酸碱滴定法、紫外法、核磁共振法及衰减全反射法[1 ] 等 ,后 3种方...
Experimental results show that the relative parameters of pH testing can be controlled in real time by using the working curve method, which enhance the accuracy of the measured pH value of the textiles.The results conform to the requirements of GB/T 7573—2009Textiles—determination of pH of ...
