Beschreibung:
The storage of phytoplankton chlorophyll a samples and the effect of MgCO3 addition to the samples were examined. The final results were calculated by different equations based on mono- or trichromatic methods. Acetone solution was used as solvent. Storage of the phytoplankton chlorophyll a samples in the cold (+4°C) and dark was possible for 24 h or even longer, without significant changes in the results. The presence of MgCO3 did not improve the keeping properties of the samples. The chlorophyll a concentrations calculated using the equation based on the monochromatic measuring method (665 nm) were identical with the results calculated by the Parsons-Strickland equation based on the trichromatic measurement.
