摘要
A Raman spectrometer includes a light source (12), a sensor element (14) and a detector (10), where the sensor element (14) includes an active surface (24), which active surface (24) is coated with a layer (26) of inert material to be placed in contact with the sample (4). A sensor element (14) includes an active surface (24) which is coated with a layer (26) of inert material. A method for obtaining a Raman spectrum using such a sensor element (14) includes the following steps: a) providing a sensor element (14), comprising an active surface (24) which is coated with a layer (26) of inert material and placing the layer (26) of inert material in contact with a sample to be analysed; b) illuminating the sensor element (14) with monochromatic light; and c) detecting surface enhanced Raman scattering by the sensor element (14).
