We have new CytoSense deployed in dutch waters! This week, as part of dutch monitoring program “Marker Wadden” one of our instruments was deployed in a buoy at Markermeer. The “Marker Wadden” monitoring program has been established in order to (i) map changes in water quality in the Markermeer; (ii) to provide insights into ecosystem functioning and (iii) to evaluate policy objectives of the program itself.

Next year the plan is to add fast repetition fluorimeter (FRRF) in the buoy, which is the best method to measure the photosynthesis activity of algae. The actual measurements of the photosynthesis activity of the phytoplankton with FRRF is crucial to acquire insight in the productivity of the Markermeer. Combining both techniques (FRRF and imaging Flow Cytometry) is particularly suitable to determine the strengths of both systems.

Moreover, our CytoSense is the only instrument present at the market which gives possibility of analysing cells of so wide size range (0.1 um in width, up to 4 mm in length) with the same configuration. As seen on attached images, at the same time you can see cells small as cyanobacteria, and big as zooplankton. Isn't that amazing?!

We are looking forward to new amazing results!

*The Marker Wadden is an artificial archipelago in development in the Markermeer, a lake in the Netherlands. The first island was inaugurated on 24 September 2016.
