Multicomponent analysis of absorption spectra (infrared or electronic spectra) by factor analysis is a suitable method to use. The algorithm of factor analysis is now available for luminescence spectroscopy. The first possibility, as in absorption spectroscopy, is to determine pure components emission spectra for a unique set of spectra of mixtures in overdetermined conditions. On the other hand, it is also possible to extract pure components emission and excitation spectra of the only data corresponding to the 3D fluorescent spectrum of a single mixture. The results are evaluated in respect to noise level and concentrations ratio on both simulated and real spectra.
通过因子分析对吸收光谱（红外或电子光谱）进行多组分分析是一种适用的方法。因子分析算法目前可用于发光光谱学。与吸收光谱学一样，第一种可能性是在超定条件下为一组独特的混合物光谱确定纯组分发射光谱。另一方面，也可以从与单一混合物的三维荧光光谱对应的唯一数据中提取纯组分发射光谱和激发光谱。根据模拟光谱和真实光谱的噪声水平和浓度比来评估结果。
