| Abstract |
Comparison between the classical spectrophotometric determinations of chlorophyll a with a fluorometric analysis preceded by high-pressure liquid chromatography, shows that interferences make the classical methods inaccurate. In extreme cases the latter induce an overestimation of the concentration up to 30 % . As the pigments are to be extracted, the extraction efficiencies of three solvents are compared. lt appears that 95 % methanol is superior comparing to DMSO and to 90 % acetone. Moreover, the efficiency improves by using a grinder. |
