Novel Raman signal generation structure

Abstract

The present invention discloses a novel Raman signal generation structure The structure comprises a light source portion and a detection probe. The light source portion is arranged in a light source generation housing which is a through-hole structure, at least one side connection hole is arranged at the outer wall of the detection probe, a rotation connection piece is arranged between the light source generation housing and the side connection hole, and the inner hole of the light source generation housing is communicated with the inner portion of the detection probe. The light source portion and the detection probe can perform relative multi-angle rotation to realize the dual functions for excitation of Raman signals through laser light source horizontal luminance and vertical luminance.

Description

technical field [0001] The invention relates to a Raman spectrometer instrument, in particular to a novel Raman signal generating structure. Background technique [0002] The laser light source part and the Raman detection probe are conventional settings for the optical system of a Raman spectrometer. The function of the Raman detection probe in the Raman spectrometer is to block the Rayleigh scattered light and collect the Raman scattering signal of the sample for analysis by the spectroscopic system. [0003] In surface-enhanced Raman scattering (SERS) technology, surface-enhanced Raman substrates include solid substrates, such as SERS substrates prepared by growing noble metal nanoparticles on various rough surfaces such as frosted glass, carbon fiber textiles, etc., and noble metal nanoparticles suspended Liquid SERS substrate in solution. When using a solid-state SERS substrate for Raman detection, a small amount of the sample to be measured is attached to the surface...

AI Technical Summary

Problems solved by technology

The detection object is a liquid SERS substrate, which is usually put into a small reagent bottle, and the sample to be tested is also added to the liquid. When using a micro-Raman spectrometer for detection, because the operator cannot fill the bottle with the liquid, the gas in the bottle will Affect the spectral detection effect, so the laser source can only be used to irradiate the liquid with no barrier to the wall of the reagent bottle

The structure between the light source part and the Raman detection probe on the traditional Raman spectroscopy instrument is difficult to meet the detection requirements for bottled liquids set in the Raman detection probe, which has great limitations on practical applications
