Instrumental Excursion

To broaden the Chemistry students’ understanding of Analytical Instrumentation the class visited Knox Innovation Opportunity & Sustainability Centre (KIOSC) at Swinburne University in Wantirna. 

Here students were provided with an unknown substance and were given the use of the laboratory to try and determine whether the powder was aspirin, paracetamol, caffeine, or pseudoephedrine. Students were able to see and use a MSGC (mass spectroscopy/gas chromatography) and IR (Infrared spectroscopy) to assist in determining the substance. These techniques can be used to determine organic compounds as discussed in AOS 1 of the Year 12 course. The students enjoyed the opportunity they were given to undertake these activities, as well as sampling university life.

The year 12 chemistry class got to explore techniques that analyse organic compounds. This was a great opportunity to get out of the classroom and apply the theory learnt in class. The students were very happy with this opportunity and not many of us get to experience putting theory into practice.

As a part of the Year 12 Chemistry curriculum, the class furthered their investigation of Organic Compounds with a trip to the Swinburne Wantirna Campus. We took part in a theoretical investigation, identifying the formula of an unknown compound, utilising several techniques. In groups of two, we undertook various experiments exploring Mass Spectrometry, Infrared Spectroscopy and Carbon and Proton NMR. 

After observing and analysing different spectra produced from the machines, we were able to identify the unknown compound to be caffeine. 

Further investigation was provided by creating five standard solutions containing an unknown concentration of caffeine, using the High Liquid Performance Chromatography machine. This allowed us to deduce the concentration of caffeine in our solution. 

Overall, the students had a great time expanding their learning, and applying their prior knowledge and study into real life applications. There was also plenty of opportunities to explore future pathways in chemistry, and STEM.
