Title: HOLOGRAPHIC SENSOR FOR DETECTION OF ADULTERANTS IN ESSENTIAL OILS AND METHOD OF OBTAINING SUCH SENSOR
Abstract:
The object of the invention is a holographic sensor for the detection of adulterants in essential oils. It consists of the use of a holographic recording technique and a photopolymer, in combination with the essential oil whose potential adulteration is to be assessed. The sensor is capable of qualitatively detecting different types of adulterants. It can also quantitively measure the degree of adulteration of an essential oil by previously calibrating the sensor for a particular adulterant. It can be miniaturised and manufactured at a reduced cost compared to traditional methods of analysis such as gas chromatography and high performance liquid chromatography. The sensor can be used by unqualifed personnel.
