Abstract
An establishing method for a Raman spectrum feature database includes the following. A Raman spectrum of at least one sample is obtained. A sample digital feature code is generated according to the Raman spectrum of the sample, in which information contained in the sample digital feature code includes information of a main peak of the Raman spectrum of the sample, and information of the main peak includes a Raman shift of the main peak and an intensity of the main peak. Also, the sample digital feature code is stored. Provided are also a composition determining method and a composition determining system.

An establishing method for a Raman spectrum feature database, comprising:
- obtaining a Raman spectrum of at least one sample;
- generating a sample digital feature code according to the Raman spectrum of the sample, wherein information contained in the sample digital feature code comprises information of a main peak of the Raman spectrum of the sample, and the information of the main peak comprises a Raman shift of the main peak and an intensity of the main peak;
- and
- storing the sample digital feature code.
A composition determining method for determining a composition of a substance to be tested, wherein the composition determining method comprises:
- providing a sample digital feature code of a sample, wherein the sample digital feature code comprises information of a main peak of a Raman spectrum of the sample;
- measuring a Raman spectrum of the substance to be tested;
- generating a digital feature code of the substance to be tested according to the Raman spectrum of the substance to be tested, wherein information contained in the digital feature code of the substance to be tested comprises information of a feature peak of the Raman spectrum of the substance to be tested, and the information of the feature peak comprises a Raman shift of the feature peak and an intensity of the feature peak;
- and
- comparing the sample digital feature code with the digital feature code of the substance to be tested, so as to determine whether the substance to be tested contains a composition of the sample.
A composition determining system for determining a composition of a substance to be tested, wherein the composition determining system comprises:
- a Raman spectrum feature database configured to store a sample digital feature code of at least one sample, wherein the sample digital feature code is generated according to a Raman spectrum of the sample, information contained in the sample digital feature code comprises information of a main peak of the Raman spectrum of the sample, and the information of the main peak comprises a Raman shift of the main peak and an intensity of the main peak;
- a Raman spectrometer configured to measure a Raman spectrum of the substance to be tested;
- and
- a processor configured to:
- generate a digital feature code of the substance to be tested according to the Raman spectrum of the substance to be tested, wherein information contained in the digital feature code of the substance to be tested comprises information of a feature peak of the Raman spectrum of the substance to be tested, and the information of the feature peak comprises a Raman shift of the feature peak and an intensity of the feature peak;
- and
- compare the sample digital feature code in the Raman spectrum feature database with the digital feature code of the substance to be tested, so as to determine whether the substance to be tested contains a composition of the sample.
