測定亞硫酸氨鈉甲萘醌注射液的手續比一般的分析要复杂一些,加上甲萘醌的化学性質又不十分稳定,若操作者在分析过程中沒有抓住关键,則所測得的含量常要比实际的低些,有时甚至虽經反复几次测定,但結果仍低。因此操作者須抓住一些主要关鍵,测定的含量才接近实际数值。我們現將从实踐中得到的一些主要經驗介紹如下,供作参考。一、方法:精确吸取亞硫酸氫鈉甲萘醌注射液25毫升(相当于亞硫酸氫鈉甲萘醌96毫克),置分液漏斗中,加氯仿30毫升,然后加10%碳酸鈉溶液15毫升,立即振搖2分鐘,依次以20毫升,15毫升振搖2次。合併氯仿,
Determination of sodium carbamazepin sulfite injection procedures than the usual analysis to be more complex, coupled with the chemical properties of menadione is not very stable, if the operator did not grasp the key in the analysis process, the measured Content is often lower than the actual, and sometimes even after repeated measurements, but the results are still low. Therefore, the operator must seize some of the key issues, the measured content is close to the actual value. We will now introduce some of the main lessons learned from practice, for reference. First, the method: precise absorption of 25 mg sodium thiourea menaquinone injection (equivalent to sodium bisulfite menadione 96 mg), set the separatory funnel, add chloroform 30 ml, and then add 10% sodium carbonate solution 15 Ml, shaken immediately for 2 minutes, followed by 20 ml, 15 ml shaken 2 times. Combined with chloroform,
