用傅立叶变换红外光谱漫反射法测药物中头孢氨苄的含量
Determination of cef alexin in capsules by FTIR - DRS
【摘要】 利用红外漫反射技术,直接测定固体药品头孢氨苄的含量,并绘制出标准曲线。与经典测定方法比较,本方法相对误差小于4%,(经典法偏差大于12%)且此方法快捷、方便、准确、无污染。
【Abstract】 This paper utilizes the techniques of infrared scanning diffuse reflection to directly determine the content of solid reagent Cafalexin, and mean while sketch its standard curve. Compared with routine methods (with their relative errors over 23 percent), this method’s relative error is below 4 percent. Moreover,the advantage of this method is also manifested in that it is time-saving,precise,and pollution-free.
