OCEAN DIAGNOSTICS
Diagnosing our planet's greatest environmental threats
STANDARDIZED. COMPREHENSIVE. RAPID.
To understand how microplastics break down, move through the oceans and freshwater systems and collect on coastlines, researchers and community monitoring groups must be able to quantify a robust set of particle size parameters.
Saturna is a portable, standardized imaging and illumination device that plugs in to your computer and syncs with a standalone analysis web application to rapidly characterize and quantify visible microplastic particles.
Use it to collect a robust set of size, colour and categorical metrics for visible microplastic samples (>400μm) like those collected from Manta trawls, neuston nets, beach quadrat samples and community studies.
FEATURES
Highly standardized built-in LED lighting system provides consistent and reproducible lighting for your microplastic samples
Compatible with any Windows PC and operated using our Mariana data portal or standalone analysis application
Provides physical size and colour data for all microplastic particles imaged
Computer pattern recognition and sizing algorithms calculate 11 discrete size calculations for every particle
Predictive colour models calculate repeatable and standardized average colour calculations for each particle
Compare your samples over spatial areas using our Mariana data portal for further insight and sample analysis
