Description

Technical Field

[0001] The utility model relates to the technical field of spectrophotometers, in particular to a photometer cell that is convenient to replace. Background Technique

[0002] A visible spectrophotometer is an analytical instrument based on the principle of ultraviolet-visible spectrophotometry, which uses the absorption of radiation in the ultraviolet-visible spectral region by substance molecules for analysis. It mainly consists of components such as a light source, a monochromator, a cell, a detector, and a signal processor. The function of the light source is to provide a continuous spectrum with sufficient intensity and stability. In the ultraviolet light region, a hydrogen lamp or a deuterium lamp is usually used. In the visible light region, a tungsten lamp or a tungsten halogen lamp is usually used. The function of the monochromator is to decompose the composite light emitted by the light source and separate the monochromatic light of the required wavelength from it. There are two types of dispersion elements: prisms and gratings. Glass cells are used for measurements in the visible light region, and quartz cells must be used for measurements in the ultraviolet light region. The function of the detector is to detect the intensity of the transmitted light through a photoelectric conversion element and convert the light signal into an electrical signal. Commonly used photoelectric conversion elements include phototubes, photomultiplier tubes, and photodiode array detectors. There are various classification methods for spectrophotometers: they can be divided into single-beam and double-beam spectrophotometers according to the optical path system; they can be divided into single-wavelength and double-wavelength spectrophotometers according to the measurement method; they are divided into spectral scanning detection and diode array full-spectrum detection according to the detection method of drawing a spectrogram. Cell: Also known as a cuvette, it is used to hold the test solution for absorbance measurement. Its bottom and two sides are frosted glass, and the other two sides are optically transparent surfaces. To reduce the loss of light reflection, the optical surface of the cell must be completely perpendicular to the beam direction. According to the material, it can be divided into two types: glass cells and quartz cells. The former is used for measurements in the visible light region, and the latter is used for the ultraviolet light region;

[0003] When the existing photometer cell is in use, the cell is usually placed at the position to be detected by the photometer for detection. After detection, the solution in the cell is emptied, and then the cell is rinsed with distilled water or organic solvent until it is clean for subsequent use. However, the existing cell is not convenient to replace, and during the movement, the solution in the cell may spill onto the photometer due to jitter, resulting in danger. To solve the above problems, a photometer cell that is convenient to replace is proposed. Content of the Utility Model

[0004] According to the above existing technical problems, the utility model provides a photometer cell that is convenient to replace, which is characterized by including a loading box, a placement groove, a limiting block, a storage groove, a cell body, a pushing groove, a working groove, a support frame, and a baffle. A placement groove is arranged below the loading box, a limiting block is arranged in the placement groove, a storage groove is arranged in the loading box, a cell body is arranged in the storage groove, a pushing groove is arranged on the loading box, a working groove is arranged on the loading box, a support frame is arranged on the working groove, and a baffle is arranged on the support frame;

[0005] Further, the placement groove is located on the photometer body. A limiting block is fixedly arranged on the placement groove. A pushing groove is arranged on the front side of the loading box. A number of cuvette bodies are arranged in the storage groove of the loading box. The height of the cuvette body is the same as the height of the storage groove. The top of the loading box has a cover plate;

[0006] Further, the working groove is located at the end of the loading box. The height of the bottom surface of the working groove is flush with the height of the limiting block. Four support frames are fixedly arranged on the surface of the working groove. A baffle is fixedly arranged on the support frame;

[0007] Further, the cuvette body is made of a transparent material.

[0008] Advantages of the utility model:

[0009] By placing the loading box into the placement groove on the photometer body, the working groove is in close contact with the limiting block. During detection, the outermost cuvette body is pushed from the pushing groove, and the innermost cuvette body is pushed onto the working groove. The opening above the cuvette body is blocked by the baffle on the support frame to prevent the solution in the cuvette body from spilling out. The photometer body detects the solution in the cuvette body. After the detection is completed, the subsequent cuvette body is pushed to move the cuvette body on the working groove to the limiting block, and this cuvette body is taken out. The next cuvette body of this cuvette body reaches the working groove and continues the detection. It is convenient to replace the cuvette. During the movement, the solution in the cuvette will not spill onto the photometer due to jitter, reducing the occurrence of danger and improving efficiency. Description of the drawings
