Interet du compteur de particules ZB-ZBI et de l'analyseur C1000 pour la numeration des algues unicellulaires de culture.
Provedor de dados: 5
Autores: Robert, Rene.
Marine unicellular algae growth rates were studied with: a Coulter Counter in conjunction with a channelizer, and a hemacytometer. Compared to the hemacytometer a good precision of the culture density was observed when the Coulter Counter was used in conjunction with a channelizer. Nevertheless care had to be taken when determining the growth of the diatoms.

Interpretation of particle spectra of electronic counters by microscopical methods
Provedor de dados: 27
Autores: Bakker, C.; Prins, T.C.; Tackx, M.L.M.
1. Using monocultures or single species dominated natural phytoplankton, cell counts and volume estimations obtained by visual and electronic methods show reasonable agreement.Calibration seems possible (Figs.1-2).2. Further examples given (Fig. 3-4) show that microscopical identification of the volume peaks in electronic counter spectra of natural seston is not quite simple. Phytoplankton peaks may not be detected in the Counter spectrum. Shifts of Counter peaks to the left side of the visual spectrum may be found when cylindrical, elongated or needle- like phytoplankton dominate the sample.3. Both visual and electronic methods include potentially large errors. Possibly particle volume is either overestimated by the microscope and / or underestimated by...
