Description

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 generated by the interaction between light and matter to analyze chemical components. When monochromatic light is irradiated on a sample, the scattered light wavelength not only contains the same component as the incident light wavelength (Rayleigh scattering), but also contains a small amount of Raman scattered light with a changed wavelength (Stokes and anti-Stokes Raman scattering), whose intensity is about 10 times the total scattered light intensity. -7 It is this wavelength-shifted Raman scattered light that provides information about the sample's chemical composition and structure. Each chemical group in the sample corresponds to a specific wavelength shift, making Raman spectroscopy a useful chemical composition fingerprint analysis technique. Raman spectroscopy has become an important analytical and research tool, eliminating the need for labeling or complex processing of samples. It is widely used in pharmaceutical, chemical, criminal evidence, materials, and medical analysis, providing chemical composition fingerprints of cells, tissues, or biofluids.

[0043] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The embodiments of the present application provide a Raman testing and analysis system, which can solve the problem that current Raman detection devices require manual sample placement every time a sample is tested, 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 slots 5 are opened inside the porous plate 4, the bottom ends of the slots 5 are transparent, and the slots 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 sample to be tested in the slot 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 which can be cylindrical, and the bottom of the slot 5 is transparent, which is used to store samples to be tested, and the number of which 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 with 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 with the excitation and collection ends of the stationary Raman signal excitation and collector 2 for detection in turn.

[0047] Specifically, multiple slots 5 within the porous plate 4 can be used to store a variety of samples to be tested in batches. The two-dimensional translation component 1 can be used to drive the Raman signal excitation and collector 2 to translate within the plane, so that the excitation end and collection end of the Raman signal excitation and collector 2 can sequentially detect the samples to be tested within the multiple slots 5. Alternatively, the porous plate 4 can be driven to translate within the plane so that the multiple slots 5 are aligned with the excitation end and collection end of the Raman signal excitation and collector 2 in turn, completing the detection of the samples to be tested in batches, reducing the large amount of manual time spent on Raman detection and improving detection efficiency. The two-dimensional translation component 1 is used to drive the movement of the Raman signal excitation and collector 2 or the porous plate 4 to perform accurate and convenient fully automatic batch Raman detection.

[0048] In one embodiment, 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 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 end of the groove 5, that is, the excitation end is aligned with the bottom end of the groove 5. Since the bottom end of the groove 5 is transparent, the laser emitted by the excitation end of the Raman signal excitation and collector 2 penetrates the bottom end of the groove 5 and detects the sample to be tested therein. Figure 2 , when the Raman signal is excited, the excitation end of the collector 2 can also be located above the bottom end of the groove 5.

[0050] In one embodiment, a transparent glass plate is sealed and installed at the bottom end of the groove 5 so that the bottom end of the groove 5 is transparent, and the thickness of the glass plate is within 100-300 microns.

[0051] In one embodiment, a glass plate with a thickness of 100-300 microns and transmittance within the wavelength range of 400-1500 nm is mounted at the top of the tank 5. This plate reduces evaporation of the liquid sample within the tank while allowing the laser light emitted from the excitation end of the Raman signal excitation and collector, as well as the Raman signal generated by the sample, to pass through the plate with low loss, ensuring signal detection sensitivity.

[0052] In one embodiment, the porous plate 4 may be made of metallic duralumin, polystyrene, BK7 glass, quartz glass or other glass that is transparent in the wavelength range of 400-1500 nm.

[0053] In one embodiment, the Raman testing and analysis system includes an oscillator 6 , on which a placement platform 3 is mounted. The oscillator drives the placement platform 3, thereby oscillating the porous plate 4, thereby achieving uniform distribution of sample particles within the wells 5 , preventing sedimentation and improving detection accuracy. The oscillator 6 can be an orbital oscillator, which uses a motor, a reducer, and a rocker to cause the porous plate to vibrate horizontally, achieving uniform mixing of the sample within the wells and preventing sedimentation of particles.

[0054] In one embodiment, the oscillator 6 includes a stepper motor and a connecting rod. The connecting rod connects the stepper motor and the porous plate to transmit power and realize piston-type vibration. Vibration is generated under the drive of the connecting rod and is suitable for scenarios such as fluid control.

[0055] In one embodiment, the oscillator 6 comprises a voice coil motor. Its operating principle is based on Faraday's law of electromagnetic induction. By varying the current, the electromagnetic force is controlled, generating vibrations driven by the voice coil motor. This is suitable for applications such as sound absorption and fluid control. When energized, the voice coil motor generates electromagnetic force, which directly drives the porous plate to vibrate. By adjusting the current, the vibration amplitude and frequency of the porous plate can be controlled.

[0056] In one embodiment, the oscillator 6 includes a buffer spring and a rotor motor. The rotor motor is installed on the porous plate, and the buffer spring is connected to the placement platform 3 and the porous plate 4 for vibration.

[0061] In one embodiment, Figure 5 and Figure 6 As shown, the two-dimensional translation assembly 1 is connected to the porous plate 4 , and the excitation end and the collection port of the Raman signal excitation and collector are located below the bottom end of the groove 5 or above the groove 5 .

[0062] In this embodiment, the Raman signal excitation and collector 2 are stationary, which reduces the impact of vibration and position deviation caused by the movement of the Raman signal excitation and collector on the Raman signal test, thereby improving the detection accuracy and making the signal excitation and collection process more stable, thereby performing accurate and convenient fully automatic batch Raman detection. Figure 5 When the excitation and collection ends of the Raman signal excitation and collector 2 are located below the bottom of the slot 5, that is, the excitation and collection ends thereof are aligned with the bottom of the slot 5, since the bottom of the slot 5 is transparent, the laser light 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. Figure 6 , the excitation and collection ends of the Raman signal excitation and collector 2 can also be located above the groove 5.

[0063] Further, such as Figure 5As shown, the Raman test and analysis system includes: an oscillator 6, a two-dimensional translation component 1 installed on the oscillator 6, and the oscillator is used to drive the two-dimensional translation component 1, thereby driving the porous plate 4 to oscillate, so as to achieve even shaking of the sample to be tested in the slot 5, thereby improving the detection accuracy.

[0067] In this embodiment, the linear motor module includes a mounting plate 11, a servo motor 12 (it can also be a stepper motor), a screw 13 and a screw slider 14. The servo motor 12 is installed on the mounting plate 11. The servo motor 12 is coaxially fixed with the screw 13. The outer wall of the screw 13 is slidably connected to the screw slider 14 to realize the linear movement of the screw slider 14 in a single-axis direction. A total of three groups of linear motor modules are set. The moving directions of the first and second groups are set in parallel. The moving direction of the third group is in the same plane as the moving directions of the first and second groups, but is perpendicular to the moving directions of the first and second groups, thereby realizing the planar movement of the porous plate 4 or Raman signal excitation and collector 2.

[0069] In this embodiment, the synchronous belt assembly includes a mounting plate, a drive motor, two rotating drums and a synchronous belt 15. The drive motor is installed on the mounting plate. A rotating drum is coaxially fixed to the drive motor. The outer walls of the two rotating drums are sleeved with the synchronous belt 15. The drive motor realizes the rotation of the synchronous belt 15. A total of three groups of synchronous belt assemblies are provided. The moving directions of the first and second groups are arranged in parallel. The moving direction of the third group is in the same plane as the moving directions of the first and second groups, but is perpendicular to the moving directions of the first and second groups, thereby realizing the planar movement of the porous plate 4 or the Raman signal excitation and collector 2, see Figure 9 To achieve this, the porous plate 4 is moved in a plane.

[0070] In one embodiment, the laser wavelength of the Raman signal excitation and collector 2 includes 405 nm, 450 nm, 480 nm, 532 nm, 785 nm, 830 nm, 990 nm or 1064 nm.
