氯霉素的含量测定,1977年版中国药典法比1963年版法有很大改进,用重氮法代替了微生物法,并用“永停”来确定终点,起到了既简便又质量好的效果。使一些医疗单位也能开展这项检验。不足之处是单位无“永停”就困难了。为此,我们用同一批氯霉索眼药水为试样,分别以紫外分光 Determination of chloramphenicol, 1977 edition of Chinese Pharmacopoeia than the 1963 version of the law has been greatly improved, with the diazo method to replace the microbiological method, and use the “permanent stop” to determine the end point, played both easy and good quality results.

To this end, we use the same chloramphenicol eye drops as a sample, respectively, by UV spectroscopy
