Total Organic Carton (TOC) Standards

Total Organic Carton Standards

Total Organic Carton (TOC) standard is a kind of reference substance used in quantitative TOC analysis. Potassium hydrogen phthalate is a common organic carbon standard. In practical use, an appropriate amount of dried potassium hydrogen phthalate is taken and diluted with water to obtain a standard solution of a certain concentration, which is called the organic carbon standard solution.

The standard solutions are diluted step by step into organic carbon standard series solutions of different concentrations, and injected into combustion tube and reaction tube respectively. The height of absorption peak on the recorder can be measured, and the corresponding concentration is plotted to draw the calibration curve. The calibration curve obtained from the TOC standards is an important basis in the quantitative analysis of TOC.
