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.
Rapid, Standardized and Smart
Saturna saves hours of time and reduces human error by automatically collecting 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, ingestion and community studies.
HOW IT WORKS
Isolate particles larger than 400μm using common collection protocols (e.g. net tows, community-based beach quadrat surveys)
Place collected particles on included background sheet beside our standardized QR code sizing reference
Place Saturna and included light-blocking shroud over top of the particles to block out external light
Collect a standardized particle image through the standalone web analysis application (included with Saturna)
Receive real-time sample image with size analysis and colour mapping created with proprietary image analysis software developed in-house
Level of classification: proprietary analysis algorithms analyze visible microplastic particles (>400µm) for physical characteristics, including 13 size and colour metrics
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 standalone analysis application
Provides physical size and colour data for all microplastic particles imaged
Computer pattern recognition and sizing algorithms calculate 13 discrete size calculations for every particle
Predictive colour models calculate repeatable and standardized average colour calculations for each particle
The application is only compatible with the Saturna Imaging System.

Saturna Case Studies
University of Tasmania processes contents from over 500 seabird stomachs with Saturna
"I never imagined there could be something like this that would make life easier for researchers.”
Fernanda Landim
Masters Student, University of Tasmania
“From a scientific perspective, Saturna helps give us so much information – it helps standardize. We can easily click through images and identify items in the seabirds, which is important for policy.”
Dr. Peter Puskic
University of Tasmania
"The Saturna Imaging system [works] by enabling better detection, monitoring and informed decision making."
