Chemistry: Shrewsbury win 3rd place in the RSC Schools' Analyst Competition Midlands Heat 2013

Tuesday 7 May 2013

Shrewsbury finished a strong third in the Midlands heat of the Royal Society of Chemistry Schools’ Analyst Competition held at Keele University on Friday 26 April.

The team of three LVI chemists, Crystal Chan (MSH), Chris Papaioannou (PH) and Ben Quirk (PH) narrowly missed out qualifying for the National Final of the competition, to be held at Reading University.

The competition involved pupils conducting team-based research using sophisticated analytical techniques used by university research scientists. This year students analysed a ‘contaminated’ pharmaceutical tablet. They measured:
•    the amount of caffeine in the tablet by HPLC (high performance liquid chromatography)
•    the quantity of aspirin in the tablet by a pH titration, and
•    the quantity of the dye (sunset yellow) in the tablet by UV-visible spectrophotometry.
