Technical Field
[0001] The present application relates to the application field of Raman spectroscopy technology, and specifically to a Raman testing and analysis system. Background Art
[0002] Raman spectroscopy is a fingerprint spectrum technology that uses inelastic scattering produced by the interaction between light and matter to analyze chemical components.

[0043] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0044] The embodiment of the present application provides a Raman testing and analysis system, which can solve the problem that the current Raman detection device needs to perform manual sampling every time it detects a sample, which is time-consuming and labor-intensive, resulting in low testing efficiency.
[0045] like Figure 1 and Figure 5As shown, an embodiment of the present application provides a Raman testing and analysis system, which includes: a porous plate 4, a plurality of grooves 5 are opened inside the porous plate 4, the bottom ends of the grooves 5 are transparent, and the grooves 5 are used to store samples to be tested; a Raman signal excitation and collector 2, the excitation end and the collection end of the Raman signal excitation and collector 2 are the same port, and the port faces the samples to be tested in the grooves 5; a two-dimensional translation component 1, the two-dimensional translation component 1 is connected to the porous plate 4 or the Raman signal excitation and collector 2, and the two-dimensional translation component 1 is configured to drive the porous plate 4 or the Raman signal excitation and collector 2 to move in a plane.
[0046] For example, the porous plate 4 is provided with multiple rows of slots 5, the volume of the slots 5 can be cylindrical, the bottom of the slots 5 is transparent, and is used to store samples to be tested, and the number of the samples can be up to 1000. The porous plate 4 and the Raman signal excitation and collector 2 are connected to the two-dimensional translation component 1 in one way, that is, Figure 1 The Raman signal excitation and collector 2 is connected to the two-dimensional translation component 1, or see Figure 5 The porous plate 4 is connected to the two-dimensional translation component 1, and the two-dimensional translation component 1 is used to drive the excitation end and the collection end of the Raman signal excitation and collector 2 to translate, and align the multiple slots 5 on the porous plate 4 for detection in turn, or drive the multiple slots 5 on the porous plate 4 to translate, and align the excitation and collection ends of the stationary Raman signal excitation and collector 2 for detection in turn.
[0047] Specifically, multiple slots 5 in the porous plate 4 can be used to store multiple samples to be tested in batches. The two-dimensional translation component 1 can drive the Raman signal excitation and collector 2 to translate in the plane, so that the excitation end and the collection end of the Raman signal excitation and collector 2 can detect the samples to be tested in multiple slots 5 in turn, or drive the porous plate 4 to translate in the plane, so that the multiple slots 5 are aligned with the excitation end and the collection end of the Raman signal excitation and collector 2 in turn, and the detection of samples to be tested is completed in batches, reducing a lot of manual time spent on Raman detection and improving detection efficiency. Use the two-dimensional translation component 1 to drive the Raman signal excitation and collector 2 or the porous plate 4 to move, and perform accurate and convenient fully automatic batch Raman detection.
[0048] In one embodiment, if Figure 1 and Figure 2 As shown, the Raman testing and analysis system also includes: a placement platform 3, the placement platform 3 is provided with a mounting hole, and a porous plate 4 is embedded in the mounting hole; a two-dimensional translation component 1 is connected to the Raman signal excitation and collector 2, and the port is located below the bottom end of the slot 5 or above the slot 5.
[0049] For example, a mounting hole is provided on the top surface of the placement platform 3, and the outer contour of the porous plate 4 can be set in a T-shape, with the narrow end of the porous plate 4 set in the mounting hole and the wide end abutting against the top surface of the placement platform 3 to prevent the porous plate 4 from falling. Figure 1 When the excitation end and the collection end of the Raman signal excitation and collector 2 are located below the bottom of the slot 5, the excitation end is aligned with the bottom of the slot 5. Since the bottom of the slot 5 is transparent, the laser emitted by the excitation end of the Raman signal excitation and collector 2 penetrates the bottom of the slot 5 and detects the sample to be tested therein.

[0051] In one embodiment, a glass plate is installed at the top of the groove 5, with a thickness of 100-300 microns and light transmittance within the wavelength range of 400-1500nm. It can reduce the volatilization of the liquid sample in the groove, and at the same time allow the laser emitted by the excitation end of the Raman signal excitation and collector and the Raman signal generated by the sample to pass through the plate with low loss, ensuring the signal detection sensitivity.
[0052] In one embodiment, the porous plate 4 may be made of metallic hard aluminum, polystyrene, BK7 glass, quartz glass or other glass that is transparent in the wavelength range of 400-1500 nm.
