“…The results on citrus oil thermal parameters show a difference, not only in thermal conductivity but also in thermal diffusivity, in addition, UV-vis spectroscopy combined with Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) were used for Orea and coworkers to reveal the chemical composition for this type of oils. 16 The obtained results confirm the values obtained by Balderas 3 and also reveal that these thermal parameters can be used as discriminant criteria to distinguish between these types of oils.…”

“…Citrus oils are composed by a complex mixture of chemical groups, in addition, the final chemical composition depends strongly on the soil, harvest time and the process used to extract the oils, therefore, is it hardly complicated to determine in a precise way quality differences among these oils. A study made on lemon and orange oils shows 0.142Wm -1 K -1 and 0.136Wm -1 K -1 values of thermal conductivity, 16 those values are the result of combining the Open photoacoustic Cell (OPC) and the Thermal Lens (TL).…”

Vegetable oils have been rising its use in several areas ranging from lubricant additives up to cosmetic industry, therefore, the price of this commodities is rising and the research for new ways to ensure the purity of the oil. By another hand, the photopyroelectric techniques, which are based on the interaction of modulated light, sample, and sensor, have proven to be a useful tool to analyze thermal properties of several kinds of liquids, in several applications. In this work, an introduction to photothermal techniques is given and based on its capabilities the reasons why this kind of techniques can be used for the analysis of samples pureness.
