1、 CAPS is used to stabilize pH values

As an excellent buffer, its main function is to stabilize the pH value of the solution. In analytical chemistry, many reactions are very sensitive to changes in pH value. Therefore, using CAPS as a buffer can effectively control the acidity and alkalinity of the solution, improve the repeatability and reliability of the reaction. For example, in acid-base titration, it can be used as a titrant to accurately determine the acidity or alkalinity of the sample by adjusting the pH value of the solution.

2、 CAPS improves the accuracy of analysis

It can also improve the accuracy of analysis. In analytical chemistry, many analytical methods require specific pH conditions. Using CAPS as a buffer can maintain the stability of the solution pH, reduce errors, and improve the accuracy of analysis. For example, in spectrophotometry, it can be used as a buffer to maintain the stability of the pH value of the solution, thereby improving the accuracy of the determination.

3、 Application of CAPS in Biochemical Analysis

In addition to being widely used in conventional chemical analysis, it also plays an important role in biochemical analysis. For example, it can serve as a buffer for enzyme reactions, providing a suitable reaction environment for enzymes and maintaining stable enzyme activity. In addition, it can also be used to prepare various biological buffer solutions, providing a suitable environment for biochemical reactions, and improving the efficiency and accuracy of the reaction.
