That is, the pre-, syn- and post-depositional alteration of chlorophyll-derivatives and carotenoids as these processes pertain to bio-organic geochemistry. The diagenesis/catagenesis of tetrapyrrole pigments and elucidation of pathways which evolve "fossil pigments" in order to employ these compounds as geochemical markers (viz. paleo ...

Figure 3. Absorption spectra of chlorophyll a and b in diethyl ether. The purity of chlorophyll can be measured by the ratio of the absorbencies of the “blue” and “red” maxima. In an organic solution, chlorophyll has two absorption maxima in the visible spectrum with wavelengths shorter than 720 nm.

– the process of separating the solid from the liquid by using a porous filter. Residue – the solid particles that remained on the filtering medium. Filtrate – the liquid that passed through the filtering medium. Water is usually one of the solvents used in the extraction process. The other liquid is usually a non-polar organic liquid.
