Description

Technical Field

[0001] The present invention relates to the technical field of nucleic acid protein detection, and more specifically, to a nucleic acid protein detector and a detection method thereof. Background Art

[0002] With the continuous advancement of science and technology, in recent years, products such as "computer collectors", "computer nucleic acid protein detectors", "dual-wavelength computer nucleic acid protein detectors", and "chromatography-conductance coupling systems" that can replace recorders have appeared on the market, greatly improving the convenience and accuracy of detection, and prompting its rapid application in many fields such as teaching experiments, scientific research, and drug production. The working principle of the nucleic acid protein detector is that the light emitted by the light source is focused to the sample pool after passing through the slit and the color filter, and then passes through the sample pool to the photocathode surface of the photomultiplier tube. The difference in sample concentration will cause the change in light intensity, which is converted into a change in photocurrent, and finally amplified by the amplifier and input into the logarithmic converter or recorder, thereby realizing the calculation of the sample concentration.

8. A nucleic acid protein detector and a detection method thereof according to claim 1, characterized in that: Two hanging rings (101) are installed on one side of the detector body (1), and the two hanging rings (101) are respectively clamped with a first limiting ring (301g) and a second limiting ring (303f), the first limiting ring (301g) is connected to a sleeve (301a), and the second limiting ring (303f) is connected to a mounting tube (303a).

9. A method for detecting nucleic acid protein, characterized in that: The steps include: S1: Connect the sampling assembly (3). When it is necessary to obtain a sample from a deeper part of the detection pool, the sampling assembly (3) is removed from the hanging ring (101), and the sleeve (301a) is inserted into the sampling port (201). The sample outlet tube (301b) is connected to the sampling port (201). When the sleeve (301a) is inserted, the movable pin (301d) is pushed open by the first inclined surface (204) of the top block (202) through the second inclined surface (301f), slides to the outside along the spring groove (301c), and after passing through the top block (202), the first spring (301e) pushes the movable pin (301d) to reset and lock the top block (202); S2: Fix and adjust the height, place the fixed clamp (302f) and the movable clamp (302g) on ​​both sides of the detection pool wall, turn the clamp adjustment screw (302h) to drive the movable clamp (302g) to tighten, so as to cooperate with the fixed clamp (302f) to clamp the detection pool wall, and at the same time turn the installation tube (303a) to adjust the height of the installation tube (303a) so that the suction structure (303) moves to a suitable height; S3: Suction the detection liquid, turn on the micro air pump (303e), the micro air pump (303e) pushes the mounting plate (303d) to move, the mounting plate (303d) pushes the suction tube (303c) to move, pushes the anti-contact blocks (304a) on both sides to move along the guide rod (304b), the second spring (304d) contracts, the suction tube (303c) moves to the outside, and then the micro suction pump (303b) is turned on to pump the liquid in the detection pool to the sampling port (201); S4: Reset and clean. After the suction is completed, the suction tube (303c) is reset, and the second spring (304d) pushes the anti-contact block (304a) to flush and seal.
