The comparison of measuring methods for Secobarbital 's content.
Abstract
The content of Secobarbital was measuring by bromimetry in Chinese Pharmacopoeia.but in the practical work, it is often measured by argentimetry,ultraviolet spectrophotometry,
high efficiency liquid spectrometry and acid-base titration,etc. After comparing and summarizing for these methods,it could be measuring by suitable methods according to different demands and needs In the practical application in order to obtain a satisfactory result .
The bromimetry is used in general examination and verification becasue this method's drug specificity is strong. The argentimetry is easy and simply to handle,so it is suitable in usual measuring. The ultraviolet spectrophotometry 's accuracy is better, and it is easier because of the continuously improving of the modern technology. The high efficiency liquid spectrometry is often used in the analysis of trace amounts of drugs in biological sample.etc. because this method is accuracy and sensitive.
