Abstract: The present inventive concept relates to a method (100) for identifying a set of candidate substances of a sample (10) using a Raman spectroscopy device (200). The method (100) comprises recording (120) a Raman spectrum using an exposure time, and recording (162) a further Raman spectrum using a further exposure time. The further Raman spectrum may exhibit Raman peaks not recorded/detected in the Raman spectrum which possibly reduces the set of candidate substances. If necessary, one or more additional Raman spectra are recorded to further reduce the set of candidate substances, such that a single candidate substance eventually remains, thereby deemed to be a substance of the sample (10). A Raman spectroscopy device (200), a computer program and a non-transitory computer-readable storage medium are also provided

Abstract: A device for detection of a substance by Raman spectroscopy comprises a holder (40) with an area (41) adapted for receiving a sample of the substance and a vibration engine (42). The vibration engine (42) is configured to move the holder (40) in a three-dimensional motion when the area (41) with the substance is arranged in front of a focusing lens (FL) of the spectrometer to provide a large actual sampling area and hence to achieve a strong signal at detection. The device comprises a SERS surface (30) arranged at the area (41) of the holder (40) for adsorption of the sample of the substance. A method for detection of a substance by use of the device is also presented.
