Results The choice of colormetric apparatus and the precision of the regents were explicit. The plating method was better in convenience and reliability than membrane-filter procedure during the microorganism inspection. Instrumental analysis is the trend of purified water inspection and deserved to be recommended. Conclusion Based on our own and others' studies, the methods of impurity analysis are improved, which might be accepted in the revision of Chinese Pharmacopoeia in future.
