How it works

MicroSTAF uses Single Turnover Active Fluorescence (STAF) to measure variable fluorescence of living phytoplankton cells enabling the evaluation of primary productivity of phytoplankton (PhytoPP). Deployed on Marine Autonomous Systems (MAS), it collects data from wider and deeper sampling areas. Integrating real-time ambient light step adjustment, automated sample exchange and spectral correction MicroSTAF delivers unparallelled sensitivity providing and globally acceptable levels of accuracy.

Where it works

Understanding the global contribution of phytoplankton to the carbon cycle requires accurate and efficient in-situ sampling and measurement across the globe. MicroSTAF offers greater versatility and is deployable across a wider range of vehicles and platforms than competing technologies enabling access to more diverse sampling and making it an ideal choice for research purposes.

How will you benefit from buying MicroSTAF?

Research into phytoplankton is essential for our understanding of the global carbon cycle and its impact on our oceans and wider environment. Stakeholders as diverse as governments, non-governmental organisations (NGO), academia, and the commercial world drive complex supply chains that demand assured results, efficiently. MicroSTAF provides accessibility to an expanded sampling area and offers pre-programmable, autonomous sample collection, that reduces operational risk and cost.

Its miniaturized design reduces its on-vessel footprint, and combined with its reduced power consumption, delivers operational efficiency while retaining trusted and acceptable measurement accuracy and sensitivity.
