Standard solutions CONCORD S050811, S050911, etc.

The standard titration solution is a high-precision standard solution, and the concentration must be accurate to the fourth decimal place. Strict monitoring and calibration of the quality of water, reagents and instruments should be carried out during preparation or calibration.

The standard impurity solution is used to detect the impurity content of chemicals and products with a certain accuracy in concentration. But it cannot be used as a standard substance for atomic absorption spectroscopy, ion chromatography, plasma spectroscopy, gas chromatography, etc., as well as for the determination of chemical reagents and the content of a chemical product.
