Abstract:
A survey conducted on 15 consecutive lots of purified sera showed that SO2-4 content in hydrolyzed fluid as satisfying the requirement, then was quantified as small value in purified sera. However, among the lots of high SO2-4 content in purified sera (SAR 12,13, SAT 13,14), it was always lower than 0.15g/l. In comparing with the SO4 standard of China’s SAT; 1g/l, the SO4 content of our preparation was 7 times lower purified sera
