摘要： A pesticide residue detection method (10) is disclosed, comprising the steps: (a) irradiating a sample to be detected by an exciting light and collecting a Raman scattered light from the sample (300); (b) acquiring a Raman spectrum of the sample from the collected Raman scattered light (400); and (c) comparing the Raman spectrum with reference Raman spectra for known pesticides in a reference Raman library to determine composition and concentration of the pesticide residue in the sample (500). The method (10) may achieve effective, convenient and accurate inspection of the pesticide residue in foods, in particular suitable for rapid detection.

摘要： A raman spectrum measuring method for drug inspection is provided, comprising: measuring raman spectrum of a sample to be inspected to acquire an original raman spectrum curve of the sample to be inspected; determining whether the original raman spectrum curve has a characterizing portion, and if not, measuring a mixture of the sample and an enhancing agent to acquire an enhanced raman spectrum curve of the sample to be inspected; and if the original raman spectrum curve of the sample to be inspected has a characterizing portion, comparing the original raman spectrum curve of the sample with data in an original raman spectrum database of the drug to determine whether the sample contains the drug, otherwise, if the original raman spectrum curve of the sample to be inspected does not have the characterizing portion, comparing the enhanced raman spectrum curve of the sample with data in an enhanced raman spectrum database of the drug to determine whether the sample to be inspected contains the drug.
