Water quality. Guidance standard on the enumeration of phytoplankton using inverted microscopy (Utermoehl technique) algolia-search-ignore and waste storageWhat is BS EN 15204 Water quality about? BS EN 15204 describes a general procedure for the estimation of abundance and taxonomic composition of marine and freshwater phytoplankton by using inverted light microscopy and sedimentation chambers, including the preceding steps of preservation and storage. Many of the general principles of the approach described may also be applied to other techniques of enumerating algae (or other entities) using a
