Abstract

A characteristic information extraction method of a small-molecule volatile substance, including: dividing a surface-enhanced Raman scattering (SERS) spectrum of the small-molecule volatile substance to obtain n wavelength subintervals, where n is a positive integer; sampling the n wavelength subintervals through weighted bootstrap sampling (WBS) to obtain W wavelength subintervals, where W is a positive integer less than n; and screening the W wavelength subintervals to obtain desired wavelength subintervals. This application also provides a rapid detection method and a portable detection system of a small-molecule volatile substance.
