用近红外漫反射光谱结合人工神经网络法对复方氨酚苯海拉明粉末药品进行快速定量分析,采用一阶导数、二阶导数和标准归一化(SNV)方法对原始光谱进行处理,建立了最佳的数学校正模型。同时预测了未知样品,预测结果令人满意。
The rapid quantitative analysis of compound paracetamol diphenhydramine powder pharmaceuticals by near-infrared diffuse reflectance spectroscopy combined with artificial neural network method was used to process the original spectra by first derivative, second derivative and standard normalization (SNV) The best mathematical correction model. At the same time, the unknown sample was predicted and the result was satisfactory.
