Abstract

The invention provides a sample rotating rack and a Raman spectroscopy detector. The sample rotatingrackcomprises a rotating body and a plurality of sample carriers arranged on the rotating body; andthe sample carriers are distributed around the circumference of the rotating body and are illuminable by light rays located around the periphery of the rotating body. The sample rotating rack is provided with as many sample carriers as possible in a space as small as possible, and optical irradiation of a plurality of samples can be quickly conducted by rotating the rotating body;the Raman spectroscopy detector comprises a laser device, a spectrum analyzer, a Raman probe, a rotating table, and the sample rotating rack; the sample rotating rack is arranged on the rotating table, the Raman probeis arranged on the periphery of the sample rotating rack, and the Raman probe is electrically connected with the laser device and the spectrum analyzercorrespondingly; and the laser device is used for emitting excitation light through the Raman probe, and the Raman probe can receive Raman scattering spectra and return to the spectrum analyzer. Raman spectroscopy detector can rapidly perform optical analysis detectionon multiple samples by using the laser device, the spectrum analyzer, the rotating table, and the sample rotating rack.

Description

technical field [0001] The invention relates to the technical field of biological science research and application, in particular to a sample rotating rack and a Raman spectrum detector. Background technique [0002] Raman scattering, also known as the Raman effect, refers to the scattering of the frequency change caused by the interaction between the incident light and the molecular motion of the medium. produced. [0003] The frequency difference between the scattered light and the incident light is called the Raman shift, and the Raman shift has nothing to do with the frequency of the incident light, it is only related to the structure of the scattering molecule itself. The size of the Raman shift depends on the change of the molecular vibration energy level, and the molecular vibrations of different chemical bonds or the inherent characteristics of the group, so the corresponding Raman shifts are also different. This is the basis that Raman spectroscopy can be used as ...
