3 Terms and definitions

There are no terms or definitions to be defined in this document:

4 Method summary

The acrylate sample passes through the chromatographic column, and each impurity is separated and detected by a hydrogen flame ionization detector: The organic impurities are normalized using a calibrated area: For quantification by the unified method, the acrylate content is calculated as 100% minus the mass fraction of organic impurities, moisture and acidity:
