Eric Zamonski Instrumental Analysis 4350L TA Seth Brittle Perfume Analysis by Gas Chromatography and Gas Chromatography/Mass Spectrometry Abstract The purpose of the experiment was to use the chromatographic techniques of GC and GCMS to distinguish between pairs of similar perfumes, one an expensive premium version, and one a cheaper “knock-off” version. Perfume pairs analyzed were Beverly Hills Giorgio, Primo Giorgio, Clinique Happy, and Perfect Scents Happy. 250 µL samples of perfume were analyzed using headspace volatile analysis, and 50 µL solutions of perfume diluted with 95% hexane were procured for liquid analysis. The analysis techniques used were indeed more than adequate to distinguish between the perfume pairs. Introduction Chromatography is one of the most useful methods of analysis available to the chemist for characterizing the composition of substances. The basic premise of chromatography is as a means of separating a substance into its constituent compounds. Although there are many types of chromatography in use today, they all have a mobile phase and a stationary phase. The mobile phase is a fluid carrier substance of some sort, either liquid or gas. This carrier fluid carries the sample substance to be analyzed down the length of a stationary phase, which interacts with the mobile phase. Different constituents of the sample interact with the stationary phase in different ways, which in turn means that they will travel at different speeds and
