Perfume Analysis

FACH2702 Practical Analysis of faker olfactory propertys Aim To determine which out of 4 un cognise hears ar genuine scents, and which are hypocrite/fake sums. This will be done by analysing gas chromatography plots, and canvass the components in the samples to that of a known cadence perfume. Results To determine which of the quadruplet sample perfumes where hypocrite and which were original, components present in each perfume were analysed apply gas chromatography and compared to the known real perfume sample. The components identified for comparison include vanillin, 3-penten-2-one, diethyl phthalate and cyclopentanaecetic acid.The congress concentration of each of the components in the samples was calculated for comparison. In the check into sample, the proportional concentration of each of these components were calculated using the area under each of the peaks (appendix 3) The homogeneous was done for unknown perfume sample 1 and it was found that while the rel ative concentrations of each component were close to the control perfume, they were not close enough to cerebrate that the sample was a real perfume, (however a truly good rip off). (appendix 4)After analysing perfume sample 2, we could conclude that this sample was an imposter perfume as there was a significant increase in twain 3-pentan-2-one and cyclopentanaecetic acid, to substitute for the loss in diethyl phthalate. (appendix 5). ingest 3 showed relative concentrations of each change that were very(prenominal) close to the control sample, thusly it was classed as a real perfume (appendix 6) It was found that sample 4s relative concentrations of each component were totally off that of the control perfume, then it is an imposter perfume. appendix 7) Discussion There werent many areas for hallucinations in this practical that would be attributed to our own human error. The gas chromatographer itself was very repeatable and hence the only error in the computers results wou ld be due to a calibration error. Another error in this experiment could be linked to the planning of the samples, some components in the perfumes are very volatile and hence if the cap were left wing off the perfume, concentrations of those components would decrease, altering the detection during analysis.Conclusion development Gas chromatography, the components vanillin, diethyl phthalate, 3-pentan-2-one and cyclopentanaecetic acid were analysed in four samples and their relative concentrations were calculated and compared to a known control perfume sample. From these calculations, it was concluded that samples 1,2 and 4 were imposter perfumes, while sample 3 had very similar relative concentrations of its compounds and was hence classed as a real perfume.
