为了筛选沉积物和化石中的有机色素，如角闪石或卟啉，建立了一种简单的漫反射紫外-可见光谱测定方法。与常见的无机颜料（如Fe 2 O3）相比，这些颜料表现出结构良好的特征吸收峰，这使得它们能够被识别。然后，这种方法被用来确定在非海百合Solenopora物种从侏罗纪的fringelite H。反射式FTIR光谱法被证明不适用于此目的。
To screen for organic pigments, like fringelites or porphyrins, in sediments and fossil specimen, a simple diffuse reflectance UV-vis spectroscopic determination was developed. In contrast to common inorganic pigments, like Fe2O3, these pigments exhibit well-structured characteristic absorption peaks which allow their recognition. This method was then used to identify fringelite H in a non-crinoidSolenopora species from the Jurassic. Reflectance FTIR spectroscopy proved not to be useful for this purpose.
