Spectres Raman de mélanges d'Huiles d'Olive et de Tournesol / Raman Spectra of Olive and Sunflower oil mixtures

About this dataset

Raman Spectra of oil mixtures (GRAPPE, Ecole Supérieure des Agricultures, INRAE, 55 rue Rabelais, 49000 Angers, France) Sampling: The document present a series of 605 Raman Spectra of different mixtures of Extra Virgin Olive Oil (EVOO) and Sunflower oil. Samples are mixture of Extra Virgin Olive Oil (EVOO) and Sunflower oil and are classify from 0 to 100% EVOO Set up Raman spectrometer QEPro (Ocean Insight, USA) set up for 785 nm with a Raman Shift: from 500 cm-1 to 2500 cm-1, a typical optical resolution of 11 cm-1 full width at half maximum (FWHM) and an integration time of 1000 ms. For all resulting spectra 10 scans were done for each acquisition. A Solid-state laser diode (Ocean Insight, USA) with an excitation wavelength of 785 nm was used with a power of 400 mW and a spectral FWHM inferior to 0.15 nm. A a general-Purpose Fiber Optic Raman Probes (Ocean Insight, USA) was used with a specific quartz cuvette holder with a working distance of 0.5mm. In accordance with our Design of Experiment 5 spectra were recorded with each mixture. Dataset organisation We present 605 Raman spectra for each line and they are organized with the following structure. Column A Acquisition date Column B Observation number for a same date Column C Spectrum number for the same mixture Column D Percentage of EVOO Column E Percentage of Sunflower oil Column F Acquisition time in ms Column G Number of scans Column H Laser Power in mW Column I Data set origin CALIBRATION, VALISATION or PREDICTION Column J to AAQ Raman intensities for different Raman Shift in wavenumbers from 500 to 2500 cm-1
