樟腦磺酸鈉溶液的含量测定,一般常采用重量法和离子交換法。重量法操作繁杂,須用时间较长,离子交换法又須用离子交换树脂和一些必需设备,不能符合医院药检工作多快好省的要求。根据上述情况,我們试用了折光计检查濃度的方法,經过試驗比较,初步认为利用折光計测定樟脑磺酸鈉的濃度,准确度能符合医院快速測定的要求,检品用量只須1～2滴即可,測定时间只須2～3分钟,大大的节約了样品用量,提高了工作效率。现將具体試驗經过分述如下:
Camphor Sulfonate solution of the content determination, usually used gravimetric method and ion exchange method. The gravimetric method is cumbersome and requires a long time. The ion exchange method has to use ion exchange resin and some necessary equipment, which can not meet the requirements of the hospital for more rapid and economical drug tests. According to the above situation, we tried the method of the refractometer to check the concentration. After the experiment and comparison, it was initially considered that the accuracy of the sodium camphor sulfonate measured by the refractometer can meet the requirements of the hospital rapid determination. Drops can be measured only 2 to 3 minutes, greatly saving the amount of samples, improve work efficiency. The specific test is now divided as follows:
