According to our understanding, the reason for this sedimentation is nothing more than the following aspects: First, the decolorized carbon used for removing pyrogen and impurities and pigments is often water Processed, which contains many chloride, if no longer be used before treatment to wash away the chloride contained therein, you can make the injection turbidity or even white floc.
