In early February, all of Year 11 had a short Zoom session about Chromatography, including the possible careers that this could lead to. Chromatography is a scientific technique used to separate and identify a mixture of compounds and is used is a wide range of industries including food testing, medicine, pharmaceutical sciences and the oil and gas sector.
We also know from advanced information from AQA, that for the 2022 GCSEs, chromatography is going to be assessed for combined science, which is another reason that pupils should understand the theory and the method for chromatography, as well as being able to analyse chromatograms.
After a review of the technique, the girls were able to use their analytical skills to identify a Pepsi thief from a line-up. The residue from each of their mugs had been tested and by comparing these chromatograms with a known Pepsi sample, the ‘Beverage Bandit’ could be identified.
