Innovative technology,
robust field-ready system

About CZE technology

Based on proven, military-grade technology, Eco Detection uses the world’s first broad-spectrum, single-suite, real-time water quality monitoring system for forensic-grade analysis.

The technology, which has miniaturised the capillary zone electrophoresis (CZE) laboratory process into a robust and field-ready system, was originally developed by Grey Innovation in conjunction with the University of Tasmania, and commercialised globally by Eco Detection’s sister spin-out company GreyScan.  In 2019, Grey Innovation won the prestigious Eureka Prize for Innovation – Outstanding Science in Safeguarding Australia with the GreyScan ETD-100 trace detection device for inorganic explosives.

The technique is analogous to US EPA Method 6500 – Dissolved inorganic anions in aqueous matrices using Capillary Ion Electrophoresis.

Eco Detection’s Ion-Q series can detect specific ions at concentrations as low as tens of parts per billion. This innovative technology uses positive and negative electrical field polarities to detect both anions and cations in sample fluid. The patented sensing system enables us to measure nitrate, nitrite, ammonium, phosphate, carbonate, fluoride, chloride magnesium, and coming soon, heavy metals, glyphosate and emerging contaminants.

In 2023, Eco Detection topped @AuManufacturing’s inaugural Top 50 Australian Manufacturers and won the Victorian iAwards23 prize for the best Sustainability and Environmental Solution.

Lab Verified

+ Patented sensing system

Eco Detection has an exclusive licence to the technology and is developing the system in partnership with Grey Innovation, an Australian technology commercialisation company.

+ Autonomous operation

Our system uses proprietary self-calibrating technology, requiring minimal user maintenance and replacement of consumables (monthly).

+ Works in any catchment environment

The high dynamic range of the sensors enables broad detection levels for upper and lower river reaches in any catchment area.

+ Remote operation and monitoring

Transmits data in real-time via mobile and satellite networks, enabling accurate trend analysis and quality assurance programs.

+ 96 data points daily

Capability for multiple daily runs for dissolved nutrients, sulphate, carbonate and chloride, and 96 data points daily for dissolved oxygen, turbidity, pH and conductivity.


Capable of operating on solar, mains or battery power, our technology is designed for remote operation and monitoring

Auxiliary sensors

The Eco Detection system is capable of deployment with auxiliary sensors to measure associated water quality parameters at the same time. This enables the system to provide a more comprehensive view of the state of the water source through the same integrated data delivery channel.

Auxiliary sensors that have been integrated with the device include; turbidity, conductivity, pH, temperature and dissolved oxygen.
