Aquamonitrix – Portable Ion Chromatograph

Source:  TH

Context: A team of scientists from the University of Tasmania has developed a portable ion chromatograph, Aquamonitrix, that allows real-time, on-site detection of nitrate and nitrite levels.

About Aquamonitrix – Portable Ion Chromatograph:

  • What It Is?
    • A compact, low-pressure ion chromatograph that can separate and detect anions (like nitrate and nitrite) in real-time, outside traditional laboratory settings.
  • Developed By: University of Tasmania researchers in collaboration with Aquamonitrix, a company specializing in field-deployable ion analysis instruments.
  • How It Works?
    • Sample Prep: Soil pore water is extracted with a portable vacuum pump and filtered on-site.
    • Separation: The device uses a short chromatographic column and sodium chloride solution as a carrier.
    • Detection: Equipped with a UV absorbance detector, it produces two clear peaks for nitrate and nitrite without interference from other anions.
    • Power: Runs on battery, enabling field portability.
  • Key Features:
    • Low-Pressure System: Simple, cost-effective, and safe for students to use.
    • Environment-Friendly: Uses sodium chloride solution instead of hazardous eluent mixtures.
    • Compact & Battery-Operated: Ideal for field studies and continuous monitoring.
    • User-Friendly: Designed for undergraduates with minimal training.
  • Applications:
    • Educational Tool: Hands-on learning for chemistry students — bridging theory and real-world practice.
    • Environmental Monitoring: On-site measurement of nitrogen cycle components (nitrate, nitrite, ammonia).
    • Research: Long-term monitoring in greenhouses, rivers, and water treatment plants.
    • Future Potential: Expansion to detect arsenic, useful for groundwater quality assessment in India & Bangladesh.
