Referring to fig. 1 and 3, the sample testing chamber 100 includes a base 101, a cover 102, a support 205, and a slide 208.

Referring to fig. 3 and 4, the base 101 has a light transmission hole 103 and an accommodating cavity 211 communicating with each other, and the light transmission hole 103 is opened in a bottom wall of the accommodating cavity 211. Slide 208 is positioned in cavity 211, and slide 208 can carry a sample (sample not specifically shown) to be tested, with the light-transmitting aperture facing slide 208. The slide 208 is optically transparent (e.g., the slide 208 can be made of quartz glass) so that the light from the raman spectrometer 500 can pass through the slide 208 and strike the sample. The cover 102 is detachably connected to the base 101, and the cover 102 covers a side of the slide 208 opposite to the light hole 103.

Referring to fig. 3 and 5, the light hole 103 is used for inserting the detecting device 501, and more specifically, referring to fig. 5, the detecting device 501 has a detecting probe 502, and the detecting probe 502 is inserted into the light hole 103. Light emitted from the detection probe 502 may pass through the slide 208 and strike the sample on the slide 208, and scattered light generated by the sample may also pass through the slide 208 and be received by the detection probe 502.

Referring to fig. 3, one method of operation of the sample testing cartridge 100 for loading a sample is generally as follows: the specimen can be placed on the slide 208, the slide 208 can be placed in the receiving cavity 211 of the base 101, and the cover 102 can be connected to the base 101 such that the cover 102 covers the slide 208. Similarly, after the assay is completed, the steps for removing the sample are generally as follows: the cover 102 is separated from the base 101, and then the slide 208 is taken out, and the sample on the slide 208 is poured out. After the sample is removed, the slide 208 may be cleaned. This sample test bin 100 self dismouting and equipment are comparatively convenient, conveniently load the sample, and conveniently take out the sample and wash sample test bin 100 after the detection is accomplished.

In the sample testing bin 100 provided by the invention, the slide 208 can be used for bearing a sample, so that the sample is prevented from falling from the slide 208 to the light-transmitting hole 103 to pollute the detection device 501; moreover, after the cover 102 is connected to the base 101, the cover 102 can cover the slide 208, which can also prevent the sample from falling.

Other specific configurations of the sample testing chamber 100 are described below.

In one embodiment, the sample testing cartridge 100 further comprises a supporting member 205, the supporting member 205 is disposed in the containing cavity 211, the slide 208 is connected to one end of the supporting member 205 near the light hole 103, the slide 208 and the supporting member 205 together define a sample containing groove 301, and the cover 102 covers and closes the sample containing groove 301. The inside surface of support 205 may hinder the sample from falling out of sample-receiving well 301, thereby further reducing the risk of the sample falling off slide 208. In the case of the support 205, the slide 208 and the support 205 may be fixed together, and then the slide 208 and the support 205 may be directly put into the accommodating cavity 211 together when a sample needs to be loaded. It should be noted that, in other embodiments, the supporting member 205 is not necessary, and the slide 208 may be directly placed on the bottom wall of the accommodating cavity 211 without providing the supporting member 205.

In an embodiment, the cover 102 and the base 101 can be connected by a screw connection. For example, referring to fig. 2 to 4, the outer surface of the cover 102 has a first screw thread 203, the side wall of the receiving cavity 211 has a second screw thread 210, and the first screw thread 203 and the second screw thread 210 are screwed with each other. More specifically, the first thread 203 may be provided on an outer circumferential surface of the main body 202.

In some embodiments, in the case of the screw connection between the cover 102 and the base 101, the distance between the slide 208 and the light-transmitting hole 103 may change with the movement of the cover 102. In this arrangement, the distance between the sample on the slide 208 and the laser source of the raman spectrometer 500 can be changed by rotating the cover 102 and adjusting the position of the cover 102 relative to the base 101, so that the light of the detection device 501 can be correctly focused on the sample, and the detection accuracy can be ensured.

For example, referring to fig. 2 to 4, in an embodiment, the sample testing chamber 100 further includes an elastic member 209, the elastic member 209 is disposed in the accommodating cavity 211, one end of the elastic member 209 is connected to the bottom wall of the accommodating cavity, the other end of the elastic member 209 abuts against the supporting member 205, and one end of the supporting member 205 adjacent to the light-transmitting hole 103 abuts against; the elastic member 209 holds the supporting member 205 together with the cover 102, thereby ensuring the positional stability of the supporting member 205 and the sealing property of the sample accommodating chamber 301, wherein the elastic force of the elastic member 209 is used for driving the supporting member 205 to move away from the light transmission hole 103.

The elastic member 209 may be configured as a spring, and the light emitted from the detecting device 501 may pass through the central space of the elastic member 209 and irradiate the slide 208. Referring to fig. 3, the elastic member 209 is in a compressed state, and if the distance between the slide 208 and the light hole 103 needs to be increased, the cover 102 can be rotated to move the cover 102 away from the light hole 103. Accordingly, the compression degree of the elastic element 209 is reduced, and the elastic element 209 is stretched to push the supporting element 205 to move, so that the slide 208 and the supporting element 205 both move away from the light hole 103. Similarly, referring to fig. 3, if it is required to reduce the distance between the object slide 208 and the light hole 103, the cover 102 may be rotated and moved to approach the light hole 103, and the supporting member 205 may be pushed to move, so that the object slide 208 and the supporting member 205 move to approach the light hole 103. Accordingly, in this process, the degree of compression of the elastic member 209 increases, and the elastic member 209 contracts. It should be noted that the supporting member 205 may not rotate together with the cover 102 during the process of rotating the cover 102.

In other embodiments, it is contemplated that no spring 209 may be disposed in sample testing compartment 100. For example, the supporting member 205 can be connected to the cover 102 by clipping, the supporting member 205 is suspended below, and when the cover 102 moves relative to the base 101, the supporting member 205 and the slide 208 connected to the supporting member 205 move together.

Referring to fig. 4, in one embodiment, support member 205 has a channel 402 and a mounting groove 401, mounting groove 401 is in communication with one end of channel 402, slide 208 is mounted in mounting groove 401, and slide 208 covers one end of channel 402 to form sample-receiving well 301. Specifically, the surface of the slide 208 facing away from the light-transmitting hole 103 serves as the bottom wall of the sample-receiving well 301, and the wall surface of the channel 402 serves as the side wall of the sample-receiving well 301. The mounting slot 401 of the support 205 may facilitate positioning of the slide 208 when assembled with the support 205. The slide 208 and the wall of the mounting groove 401 can be connected by adhesion.

More specifically, referring to fig. 4, in an embodiment, the supporting member 205 includes a first cylinder 206 and a second cylinder 207, the diameter of the first cylinder 206 is smaller than that of the second cylinder 207, and the first cylinder 206 and the slide 208 are respectively connected to both ends of the second cylinder 207; a part of the passage 402 is disposed inside the first cylinder 206, another part of the passage 402 is disposed inside the second cylinder 207, and the mounting groove 401 is disposed inside the second cylinder 207. That is, the support 205 has a stepped cylindrical structure. With reference to fig. 2 to 4, the cover 102 is disposed outside the first cylinder 206, and more specifically, the main body 202 of the cover 102 is disposed outside the first cylinder 206; one end of the second cylinder 207 close to the first cylinder 206 abuts against the end surface of the cover 102, that is, the top end surface of the second cylinder 207 abuts against the bottom end surface of the cover 102. The cover body 102 is sleeved outside the first cylinder body 206, so that radial positioning between the cover body 102 and the supporting piece 205 can be realized; the second cylinder 207 abuts against the end face of the cover 102, so that the cover 102 and the support 205 can be axially positioned, and the sealing effect on the sample accommodating groove 301 can be improved.

Referring to fig. 2 to 4, in an embodiment, the cover 102 includes a main body 202 and a cover glass 204, the main body 202 is connected to the holder body 101, and the cover glass 204 is connected to the main body 202 and covers the sample receiving groove 301. Both the cover glass 204 and the slide 208 may be made of quartz glass. The cover glass 204 is provided primarily to improve the accuracy of the test. Specifically, for some samples (e.g., film-like samples), the light emitted from the detecting device 501 may penetrate through the sample and irradiate the cover 102, so that the spectrum collected by the detecting device 501 includes the scattering spectrum of the material of the cover 102, which affects the accuracy of the detection. Since the raman scattering of glass is weak and has little influence on the spectrum collected by detection, covering the sample accommodating groove 301 with the cover glass 204 can reduce the influence of the scattered light of the cover body 102 on the detection result, thereby improving the accuracy of detection.

In addition, in order to improve the detection accuracy, in an embodiment, the main body 202, the seat body 101 and the supporting member 205 can be made of a material that is opaque to light, so that the ambient light can be prevented from being incident into the sample-accommodating groove 301, and the ambient light can be prevented from interfering with the scattering spectrum of the sample. The opaque material may be opaque plastic, metal, or the like, and the materials of the main body 202, the seat 101, and the support 205 may be the same or different, as long as they can isolate the ambient light, which is not specifically exemplified herein.

As mentioned above, the sample can be placed in the sample holding tank 301, and this way of placing the sample can be applied to the liquid-based or powder-based sample. For a film-like sample, it is considered that the sample is placed in the sample holding tank 301; alternatively, it is conceivable to clamp the edge of the sample by the support 205 and the cover glass 204, thereby achieving loading of the film-like sample.

Specifically, referring to fig. 3, in an embodiment, an end surface of the support 205 near one end of the cover glass 204 is covered by the cover glass 204, and there is a gap (which is not specifically labeled) between the end surface of the support 205 near one end of the cover glass 204 and the cover glass 204. With the specific orientation of fig. 3 as a reference, there is a gap between the upper section of the support 205 and the lower surface of the cover glass 204. An edge portion of the thin-film like sample may be disposed in the gap, i.e., the edge of the thin-film like sample may be clamped by the cover glass 204 and the support 205. The central region of the film-like sample is shielded above the sample holding well 301, and the light emitted from the detection device 501 can pass through the slide 208 and the sample holding well 301, and thus can be irradiated to the sample. The advantage of using the cover glass 204 and the supporting member 205 to clamp the edge of the film-like sample is that the edge portion of the sample can be fixed, the material can be prevented from moving greatly due to the shaking of the sample testing chamber 100, and the material can be prevented from wrinkling and curling, so as to improve the detection accuracy of the film-like sample.

In the case where it is desired to sandwich the edge of the sample between the support 205 and the cover glass 204, the sample is loaded in a manner generally as follows: after the cover glass 204 is completely connected to the main body 202, the main body 202 in fig. 4 needs to be turned upside down, the sample is placed on the cover glass 204, then the supporting member 205 is covered on the sample, and the holder body 101 is reversely buckled on the outside of the supporting member 205.

Referring to fig. 4, in an embodiment, an end of the main body 202 near the light-transmitting hole 103 has a receiving groove 403, the cover glass 204 may be disposed in the receiving groove 403 and connected to a wall surface of the receiving groove 403 (for example, the cover glass 204 is fixed to the main body 202 by adhesion), and the first cylinder 206 may be disposed in the receiving groove.

The invention further provides a raman spectrometer 500, wherein the raman spectrometer 500 comprises a detection device 501 and the sample testing chamber 100 in any of the above embodiments. The detection device 501 includes a detection probe 502, and an end surface of the detection probe 502 can emit light and collect scattered light. The detection probe 502 is detachably connected with the sample testing chamber 100, the detection probe 502 is disposed in the light-transmitting hole 103, and the end face of the detection probe 502 faces the slide 208.

In the raman spectrometer 500 of the present invention, since the sample is not easily dropped from the slide 208, and the sample testing chamber 100 is easily and conveniently disassembled and assembled, the loading efficiency of the sample is high, and the detection efficiency of the raman spectrometer 500 is high.

In one embodiment, the raman spectrometer 500 is provided as a portable instrument. That is, the raman spectrometer 500 as a whole can be operated by a user holding the raman spectrometer in his hand like a mobile phone. The portable raman spectrometer 500 is convenient for the user to carry, and the user can take the raman spectrometer 500 to different locations, which means that the detection of the sample need not be confined to a particular laboratory.

The detection device 501 may have a display screen 503, in an embodiment, the display screen 503 may be a touch screen, a plurality of virtual keys capable of being touched by a user may be displayed on the display screen 503, and the user may operate the raman spectrometer 500 by touching the display screen 503. For example, after the user presses the "start" button on the display 503, the raman spectrometer 500 starts to automatically detect the sample, the detection probe 502 of the detection device 501 emits light and collects scattered light, and after a certain period of time, the test result can be shown on the display 503. Alternatively, in another embodiment, the display screen 503 is a non-touch screen, and the detection device 501 is further provided with a physical button, so that the user operates the raman spectrometer 500 by touching the physical button, thereby enabling the raman spectrometer 500 to automatically detect the sample in the sample testing chamber 100.

In an embodiment, the base 101 includes a connection key 104, the connection key 104 is protruded from a wall surface of the light transmission hole 103, an outer peripheral surface of the detection probe 502 has a connection groove 600, and the connection key 104 is clamped in the connection groove 600. The exterior of the connecting key 104 may abut against the walls of the connecting slot 600, thereby preventing the sample testing cartridge 100 from falling off the test probe 502. When it is desired to remove sample testing cartridge 100, the user may apply a slight force to remove sample testing cartridge 100, thereby disengaging coupling keys 104 from coupling slots 600. The advantage of this arrangement is that the convenience of connection or detachment between the sample testing cartridge 100 and the test probe 502 is high, and it is not necessary to use tools such as a screwdriver, and it is not necessary to perform troublesome operations such as screwing.

In an embodiment, the connection key 104 may be provided as a dot-shaped protrusion, and accordingly, the connection groove 600 may be provided as a dot-shaped protrusion. In another embodiment, to further improve the ease of assembly and disassembly between the sample testing cartridge 100 and the test probe 502, the connecting slot 600 may be configured in the shape shown in fig. 6. Referring to fig. 6, the connection groove 600 includes a first extension 601 and a second extension 602, the first extension 601 extends along an axial direction of the detection probe 502, the second extension 602 extends along a circumferential direction of the detection probe 502, the end surface of the detection probe 502 further has an opening 603, two ends of the first extension 601 are respectively connected with the opening 603 and one end of the second extension 602, the opening 603 is used for the connection key 104 to pass through, and the connection key 104 can slide in the first extension 601 and the second extension 602.

In the embodiment shown in FIG. 6, the connection between the sample testing cartridge 100 and the test probe 502 is generally as follows: the connecting key 104 enters the first extension 601 from the opening 603, and then the connecting key 104 slides along the first extension 601; after the connection key 104 slides to the connection position between the second extension portion 602 and the first extension portion 601, the connection key 104 slides along the second extension portion 602, and finally the connection key 104 is clamped at one end of the second extension portion 602 away from the first extension portion 601.

Similarly, the steps of separating the sample testing cartridge 100 from the test probe 502 are generally as follows: the connection key 104 is first slid along the second extension 602 to the connection between the first extension 601 and the second extension 602, and then the connection key 104 is slid along the first extension 601 until the connection key 104 leaves the first extension 601 from the opening 603.

For the embodiment shown in fig. 6, in the process of connecting or separating the sample testing chamber 100 and the detecting probe 502, the connection key 104 slides along the first extension 601 and the second extension 602, and the user does not need to laboriously deform the light hole 103 in the radial direction to separate the connection key 104 from the connection slot 600, so that this embodiment is beneficial to improving the convenience of assembling and disassembling the sample testing chamber 100 and the detecting probe 502.

In one embodiment, the connection or disconnection between the sample testing cartridge 100 and the test probe 502 may be by some drive mechanism. For example, the outer circumferential surface of the sample testing chamber 100 may be clamped by a clamp driven by a motor, and then the motor drives the clamp to rotate at a certain angle so as to move the motor-driven sample testing chamber 100 along the second extension 602; next, an air cylinder connected to a motor may be activated, which drives the motor and the clamp in a straight line, thereby moving the sample testing chamber 100 in its axial direction and separating it from the sensing probe 502. In this manner, automatic disassembly of the sample testing cartridge 100 may be achieved.
