**Bengaluru -** In a move that could revolutionize chemistry education and environmental monitoring, scientists at the University of Tasmania have developed a portable ion chromatograph that allows students to conduct real-time analysis of pollutants in the field.
Traditional ion chromatography, used to separate and analyze ions in a sample, requires expensive and complex laboratory equipment. Now, with the Aquamonitrix, students can extract soil pore water, filter it on-site, and immediately analyze concentrations of harmful nitrate and nitrite ions.
Published in the *Journal of Chemical Education*, the research demonstrates that the portable device produces results comparable to traditional lab equipment, but at a fraction of the cost and time. The device, costing around $10,000, can be battery-operated and is user-friendly, allowing students without extensive training to perform accurate analysis.
“We don’t want to do everything,” explained Professor Brett Paull, the lead researcher. “It’s not possible to take a $100,000 laboratory instrument and just take it out to the greenhouse and use it. What we do is develop a $10,000 instrument which actually can do one or two things very well… We’re not trying to replicate the lab in the field; we’re trying to develop low cost, versatile instruments that can be taken into the field.”
The portable chromatograph separates anions using a short column and a sodium chloride solution, making the process environmentally friendly. A low-cost UV absorbance detector identifies nitrate and nitrite ions, producing a simple, clear chromatogram.
The device is also being adapted to detect ammonia levels and, crucially, arsenic in contaminated soils, a significant problem in countries like India and Bangladesh where groundwater extraction is high.
The broader implications are significant. As Dr. Vipul Gupta from Deakin University points out, “By allowing students to perform both field and laboratory analyses, [the portable device] provides a comprehensive learning experience that combines theoretical concepts with practical applications… The hands-on nature of the experiment, coupled with the opportunity to address real-world environmental challenges, fosters curiosity and interest in analytical chemistry.”
The development promises to enhance science education and provides a practical tool for environmental monitoring, particularly in regions facing water contamination issues. The team hopes to encourage the development of more innovative analytical chemistry projects using such portable systems.
