| 摘要 |
An analyser and a method for identifying or verifying a liquid based drug sample (16) are disclosed. The analyser comprises an electromagnetic radiation source (11) for emitting electromagnetic radiation (14a) in at least one beam at a sample (16); a sample detector (17) that detects affected electromagnetic radiation resulting from the emitted electromagnetic radiation affected by the sample and provides output representing the detected affected radiation and a processor (18) configured to query a database of reference drugs for identifying or verifying the sample from the detector output representing the detected affected electromagnetic radiation. The electromagnetic radiation comprises at least two different wavelengths. Each wavelength or at least two of the wavelengths is between substantially 1300nm and 2000nm, and each wavelength or at least two of the wavelengths is in the vicinity of the wavelength(s) of or within a region spanning a spectral characteristic in the liquid spectrum between substantially 1300nm and 2000 nm. |
