Portable Ion Chromatography Brings Real-World Practice to Classrooms

• Scientists at the University of Tasmania in Australia have developed a portable ion chromatograph, Aquamonitrix, to perform ion chromatography in the field.

• The device, which uses a low-pressure ion chromatograph, can separate anions along a short column and is environmentally friendly.

• The solution used to carry the sample into the chromatograph and facilitate the exchange of anions with the column contains only sodium chloride, making the process environmentally friendly.

• The device uses a low-cost absorbance detector that uses ultraviolet light to identify nitrate and nitrite ions.

• The resulting chromatogram displays two distinct peaks corresponding to the presence of the two anions.

• The portable chromatograph produced results comparable to that of a conventional lab device.

• The researchers collaborated with Aquamonitrix, the company that manufactures the portable ion chromatograph, to help young undergraduate students analyse samples in the field.

• The portable method provided accurate results and was more cost-effective and time-efficient than lab-based ion chromatographs.

• The team is also working on a similar instrument that can measure ammonia levels in the field.

• The portable device provides a comprehensive learning experience that combines theoretical concepts with practical applications, fostering curiosity and interest in analytical chemistry.

Real-world science practice is important topic for Civil service exam (WBCS).
