用红外光谱法进行混合物的定量分析,需先选择好混合物光谱中各个组份的特征吸收峰位置,读出相应吸收峰的吸光度,结合 Beer定律,解联立方程求解,实际只利用了几个特征峰的数据点,如果是对全部光谱图吸收峰的整段数据进行求解,定量结果必然更可信,因为至少减小了随机误差。随着红外光谱仪和微机联用,光谱数据数字化技术的普遍化,上述设想是容易实现的。 The quantitative analysis of the mixture by infrared spectroscopy, you must first select the mixture peak position of each component of the characteristic spectrum, read the absorbance of the corresponding absorption peak, combined with Beer’s law, solution of simultaneous equations to solve, the actual use of only a few If the data points of the characteristic peak are solved for the entire data of the absorption peak of all the spectra, the quantitative result is necessarily more credible because at least the random error is reduced. With the common use of infrared spectroscopy and micro-computer and the digitization of spectral data, the above assumptions are easy to implement.
