鹽酸氨胍的含量测定方法以銀量法較为方便。惟此法由于氯化銀沉淀易于膠化(車間生产中的返工品膠化情况更为严重),影响濾过速度;而沉淀太細,穿过滤紙,使結果不正确,为其缺点。我們曾进行試驗,作了一些改进,不至产生膠化,一般在三小时內即可测定完畢。經过一年来的採用及观察,未發生異常現象,故加以介紹。操作方法:取鹽酸氯胍片20片,精密秤定重量,研细,精密秤取适量(約与鹽酸氯脈0.5克相当),置于100毫升容量瓶中,加入硝酸硝酸铵溶液40毫升(1000
Determination of the amount of aminoguanidine hydrochloride method is more convenient. However, this method because of silver chloride precipitation easily gelatinized (workshop production rework gel more serious), affecting the filtration rate; and precipitation too fine, through the filter paper, the result is incorrect, as its drawbacks. We have conducted tests, made some improvements, not to produce gel, usually within three hours can be measured. After a year of adoption and observation, there is no abnormal phenomenon, so be introduced. Method of operation: take chloroguanidine hydrochloride tablets 20, precision scale set weight, fine grinding, precision scales take about (equivalent to about 0.5 grams of hydrochloric acid chloride), placed in 100 ml volumetric flask, add ammonium nitrate solution 40 ml ( 1000
