Abstract

The invention discloses a raman spectrum enhancement measuring system which comprises a grating spectrometer, a light emitting/receiving probe, a sample tank and a laser light source, wherein the sample tank is a liquid core waveguide tube sample tank, the liquid core waveguide tube sample tank comprises a liquid core waveguide tube, the liquid core waveguide tube is arranged in a sealed chamber,an incidence window is arranged on the sealed chamber and at the position right facing a pipe opening of the liquid core waveguide tube, an emergence window is arranged on the sealed chamber and at the position right facing the other pipe opening of the liquid core waveguide tube, the laser light source can irradiate the incidence window of the sample tank through an exciting light path in the light emitting/receiving probe, and the emergence window of the sample tank can irradiate the grating spectrometer through a signal detecting light path in the light emitting/receiving probe. The raman spectrum enhancement measuring system disclosed by the invention can solve nonlinear and uneven enhancement phenomena in gold, silver and the like nano enhancement technologies and makes up the problemthat an enhancement effect of liquid core waveguide is insufficient at the same time, so that the raman enhancement technology can achieve better application in pesticide residue detection.

Description

technical field [0001] The invention relates to a spectrum measurement system, in particular to a Raman spectrum enhanced measurement system, which is used for the detection of solution substances, such as water quality detection, drug residue detection, illegal food additive detection and other detection fields. Background technique [0002] The incident photon excites the electron to a high-energy virtual state, and the electron then de-excites to a low-energy state, emitting scattered photons. If the energy levels of the initial state and the final state of the electron are the same, then the energy of the scattered photon is equal to that of the incident photon, which is called Rayleigh scattering; and if the energy level of the initial state and the final state of the electron is different, then the energy of the scattered photon is different from that of the incident photon, which is called Rayleigh scattering. for Raman scattering. When the energy level of the final ...
