TECHNICAL CAPABILITY

AND SPECIFICATIONS

The Aquamonitrix® system is based on rapid ion chromatography, employing a simple anion exchange method.

Selective, direct detection of nitrite and nitrate is attained through the use of a novel, patented optical detection technology.

The system is cost-effective and delivers highly accurate and precise analytical performance even compared to leading laboratory-based instrumentation*.

*Based on validation trials by the US EPA

Laboratory – Quality Performance

lab quality

Laboratory versus Aquamonitrix® performance in trials carried out as part of the US Environmental Protection Agency (EPA) Advanced Septic System Nitrogen Sensor Challenge. The one-month trials were carried out at the Massachusetts Alternative Septic System Test Center (MASSTC), a US National Sanitation Foundation (NSF) certified test facility in Barnstable, Massachusetts.
