Raman spectrum measuring method for drug inspection

A raman spectrum measuring method for drug inspection, comprising the steps of:

• (a) measuring raman spectrum of a sample to be inspected to acquire an original raman spectrum curve of the sample to be inspected;
• (b) determining whether the original raman spectrum curve of the sample to be inspected has a characterizing portion or not, and if not, measuring a mixture of the sample to be inspected and an enhancing agent to acquire an enhanced raman spectrum curve of the sample to be inspected;
• and
• (c) 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 to be inspected with data in an original raman spectrum database of a drug to determine whether the sample to be inspected 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 to be inspected with data in an enhanced raman spectrum database of a drug to determine whether the sample to be inspected contains the drug.
