Problems solved by technology

[0005] In general testing, multiple tested samples in 4 situations composed of two conditions of substance type and substance solution concentration are numbered and measured sequentially. Since the commonly used sample pool only provides single-channel measurement, it is easy to not pay attention to this. to confuse
And increase the number of operations, error-prone

Abstract

The invention discloses a multi-channel focusable sample tank implementing raman spectrum detection. The multi-channel focusable sample tank comprises a base, a support, a sample holding and rotating mechanism, a vertical displacement mechanism and a horizontal displacement mechanism, wherein the sample holding and rotating mechanism is connected with the support through the vertical displacement mechanism; the support is connected with the base through the horizontal displacement mechanism; the sample holding and rotating mechanism comprises a bracket, and a sample holding seat, a stepping motor and a control unit, which are arranged on the bracket; the stepping motor is connected with the sample holding seat and drives the sample holding seat to rotate; the control unit is electrically connected with the stepping motor. With the adoption of the multi-channel focusable sample tank implementing raman spectrum detection, different samples can sequentially correspond to incidence laser without causing confusion; repeated replacing of sample bottles is avoided so that the time is shortened; meanwhile, the labor intensity of experimenters is relieved and the error possibility is reduced.

Description

technical field [0001] The invention belongs to the technical field of Raman spectroscopy equipment, in particular to a Raman spectroscopy detection multi-channel focusable sample cell. Background technique [0002] Academician of the Chinese Academy of Sciences and Professor Tian Zhongqun's research group from the School of Chemistry and Chemical Engineering of Xiamen University proposed the establishment of a technology called "Shell-isolated Nanoparticle Enhanced Raman Spectroscopy" (Shiners technology), which is equivalent to spreading a layer of chemical inertness on the surface of metal or other materials. Gold nanoparticles isolated by ultra-thin shells of materials can enhance the Raman spectrum of various material surfaces by using these nanoparticles. [0003] When using this technique to measure Raman spectra, it is often necessary to perform comparative measurements in various situations according to the type of substance and the concentration of the substance so...
