Introducing the all new LabSTAF Single Turnover Active Fluorometer system

Single Turnover Active Fluorometry (STAF) can measure Phytoplankton Primary Productivity (PhytoPP) on much wider spatiotemporal scales than is possible with more direct methods such as 14C fixation. "Over the last ten years, we have worked closely with the research community to develop hardware and data processing algorithms that bring us closer to realising this potential. Our combination of FastOcean STAF sensor and Act2 laboratory system is highly successful and the LabSTAF system builds upon this. It incorporates a number of new features that are specifically designed to minimise errors associated with the conversion of STAF data to PhytoPP," said Dr Kevin Oxborough.

Chelsea supplies Idronaut SRL with new 2000M rated TriLux Fluorometer

Chelsea Technologies are pleased to supply Idronaut Srl with the new 2000m rated TriLux configured for measurement of Chlorophyll-a, Phycoerythrin and Turbidity for integration to their Ocean Seven series of CTD’s.  The increased depth capability of the popular miniature multi-channel fluorometer has made this an ideal addition to the Ocean Seven multiparameter Sonde.  Chelsea have been providing Idronaut with TriLux fluorometers since its original launch, including OEM versions for direct integration to the Sonde.

Chelsea ALGAE-Wader system used to monitor HABs in Berlin’s bathing waters

“When the State of Berlin-Brandenburg were experiencing toxic algae blooms in their urban bathing areas last year, they needed a simple, reliable but accurate portable system to monitor these cyanobacteria blooms that would measure not only the algae pigments Chlorophyll a and Phycocyanin, but also Phycoerythrin,” said Justin Dunning. “We supplied the State Laboratory of Berlin with an ALGAE-Wader Pro system to cover these requirements and we’re delighted to announce they have placed further orders.”  

Chelsea TriLux successfully installed on new robot from Blooming Robotics

A new robot has been developed in a collaborative project between Blooming Robotics and Technical University Delft for removing cyanobacteria from open waters. Current methods for killing cyanobacteria, such as using hydrogen peroxide, damages the surrounding nature and leaves nutrients available for new blooms.

As part of this system, the Chelsea low cost TriLux Fluorometer has been installed on the front of the vessel via an Arduino platform and is used  to measure chlorophyll and phycocyanin. Once a specific threshold is passed, the system transitions into an algae-harvesting state.

Finnish Environmental Institute (SYKE) took delivery of two further UniLux fluorometers for use in their Baltic Sea monitoring program for cyanobacteria

“We recently supplied the Finnish Environmental Institute (SYKE) with a further two UniLux fluorometers. This follows on from the supply of three sensors last year for use in their Baltic Sea monitoring program for cyanobacteria,” reports Sam Kirby.

The new sensors are part of the Institute’s plans for developing flow-through systems, fixed platforms and laboratory experimental set-ups that require smaller fluorometers.
