Description

Technical Field

[0001] The utility model belongs to instruments and equipment in the application field of high-spectrum remote sensing technology, and specifically relates to a special spectrometer for detecting heavy metal chromium in human hair. Background Art

[0002] Chromium is involved in the metabolism of sugar and fat in the human body and is an essential trace element for the human body. Chromium deficiency in the human body can cause obesity and even diabetes, while excessive chromium content can cause circulatory disorders in the human body and affect human health. Chromium can exist in human hair and blood.

[0003] At present, the detection methods for trace element content in hair are becoming more and more diversified, and multiple elements can be continuously detected from a sample. The widely used detection methods are: atomic absorption spectrometry, inductively coupled plasma emission spectrometry, and reversed-phase ion pair high performance liquid chromatography. These detection methods are all chemical methods, and the hair sample needs to be pre-treated before detection. At present, wet digestion is mostly used for pre-detection treatment. This method requires destroying the sample to release the inorganic components to be tested. Compared with chemical detection methods, the advantage of hyperspectral is that no pre-treatment operation is required and the efficiency is high. However, due to the thinness of hair, light leakage is easy to occur during measurement, which affects the detection data. Therefore, the existing spectrometer is not suitable for direct detection of hair. Utility Model Content

[0004] The purpose of the utility model is to solve the defects of the prior art and propose a special spectrometer for detecting heavy metal chromium in human hair. The spectrometer has the advantages of simple operation, uniform sample spreading and less sampling.

[0006] Preferably, the sliding opening is located at one side of the base and is sunken, and its width is just enough to accommodate the bottom box.

[0007] Preferably, the sealing strip is a black silicone strip to prevent light from entering the bottom box and the detection port.

[0008] Preferably, the bottom plate is a square plate with a side length of 10-15 mm.

[0009] Preferably, the plane where the bottom plate, the fixed comb and the magnet are located is higher than the height of the sealing strip, and they extend deep into the detection port to reach below the detection unit for detection.

[0010] Preferably, the fixed comb and the movable comb are provided with comb teeth on one side surface, the comb teeth have a height of 0.05-0.1 mm, a comb teeth spacing of 0.05-0.1 mm, and the total length of the comb teeth after arrangement is 5-8 mm longer than the side length of the bottom plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects: first, the design is simple and reasonable, and it is easy to use, and it is easy to transform and upgrade the existing handheld spectrometer; second, it has good light-shielding properties, and can avoid light interfering with the detection results during detection; third, only a small amount of hair is needed to cover the bottom plate, and the sampling amount is small.
