Different brands of chromatography grade and gradient grade reagents, although the requirements for the indicators may varyThe same, but the indicator items are basically the same. Generally, gradient grade reagents have stricter requirements on low wavelength gradients. Their common indicators include content, density, chromaticity, evaporation residue, moisture, acidity and alkalinity, absorbance, gradient elution test, and fluorescence analysis. We divide these indicators into three categories:

General indicators: such as density, boiling range, refractive index, etc., as long as the substance is pure acetonitrile, these indicators are relatively fixed.

Important indicators such as content, moisture, acidity, alkalinity, and evaporation residue are the basic requirements for chromatographic reagents. The vast majority of commercially available chromatographic products meet these requirements, and the difference in test results is not significant.

Key indicators: absorbance, gradient elution test. At present, in acetonitrile products, the differences between samples can be clearly detected from key indicators when there is little difference in important indicators. It is very important to control the detection conditions of key indicators.
