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.

The technology, which has miniaturised the capillary zone electrophoresis (CZE) laboratory process into a robust and field-ready system, was originally developed in conjunction with the University of Tasmania, and commercialised globally in Eco Detection’s sister company GreyScan’s ETD-100, a trace detection device for inorganic explosives.  In 2019, GreyScan won the prestigious Eureka Prize for Innovation – Outstanding Science in Safeguarding Australia. During 2020, the company pivoted to GreyScan to develop and commercialise its innovative screening platform to produce the TVD-1 & TVD-2; two products, which are capable of detecting viruses including SARS-COV-2.

Eco Detection 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. This patented sensing system enables us to measure nitrates, nitrites, ammonium, phosphates, chloride and coming soon, heavy metals, glyphosate and emerging contaminants.

Industry Standard Once per Month


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.
