Aquamonitrix Handheld Field Environmental Ion Chromatography

An innovation in the field of analytical chemistry has taken the ion chromatography, which was a preserve of advanced laboratories, to the arena. Scientists at the University of Tasmania have come up with a nitrate and nitrite detecting ion chromatograph, called Aquamonitrix, which is a portable device that could help detect nitrate and nitrite in the soil pore waters in real-time. Such innovation makes environmental monitoring cheaper, accessible and practical and is also a useful educational instrument.

Making Ion Chromatography easier.

The principle of the ion chromatography is to separate the ions as they flow through a column. Traditional tools employ long columns, high-pressure pumps, and sophisticated detectors, which are costly and complicated. Contrary, Aquamonitrix uses a short column, low-pressure pump, and sodium chloride solution as a mobile phase. This non-toxic and easy to set up setup enables the device to detect nitrate and nitrite ions based on UV light absorbance, and hence the interference of other ions is eliminated.

Field Application

The device is field work oriented. A portable vacuum pump gathers soil pore water samples which are gathered by the students or researchers. The sample is filtered and directly injected into Aquamonitrix. The instrument produces chromatograms with nitrate and nitrite concentrations in minutes, and gives real-time information about the conditions in the environment. These findings are then confirmed in laboratory by conventional ion chromatography and experiments indicate that the two techniques are very similar.

Benefits against traditional Systems.

Although the ion chromatography technique in laboratories has the ability to screen numerous types of ions, it is large, expensive, and cannot be deployed in the field. Aquamonitrix, which is approximately ten times cheaper than conventional systems, is battery operated, small and very dependable in analyzing nitrate and nitrite. It does not fully substitute laboratory instruments; however, it is suitable when applied to the environment in specific settings.

Educational and Environmental Impact.

Aquamonitrix is also useful in environmental monitoring as well as in teaching chemistry. The students have real-life field experience and can relate theory to practice. The device can be used especially to monitor soil and water pollution by nitrogen, a problem associated with agricultural run-off and ecosystem erosion.

Future Outlook

Researchers are also extending the technology to other pollutants like ammonia and arsenic, which would solve wider issues related to the environment and the overall health of the people. Aquamonitrix will be able to change the way pollution is monitored and how agriculture is managed in remote and resource-constricted areas due to its affordability, portability, and precision.
