One of the most important index in oceanography, phytoplankton biomass, is based on determination of chlorophyll a, an algae pigment. Unlike higher plants, algae show in their composition a large number of pigments broadly called accessory or photosynthetic pigments. These pigments include chlorophylls, carotenoids and phycobiliproteins. Measuring the relative or absolute concentration of algae pigments is a powerful tool to study algae phylogeny, taxonomy, physiology, ecology and others. Chlorophyll a concentration is determined in natural samples either by spectroscopy or fluorometry. In the other hand, the determination of other photosynthetic pigments, such as carotenoids, is difficult due to their close absorption characteristic and th...
