Abstract

The invention discloses a device and method for rapidly detecting the content of antibiotics in camel milk or donkey milk. The device comprises a base and two sets of vertical plates connected to the top of the base, a test tube rack is arranged between the two sets of vertical plates, an extraction rack is installed on the tops of the vertical plates, and a plurality of extraction tubes are evenly arranged on the extraction rack; the extraction rack comprises a positioning plate and two side plates connected to the bottom of the positioning plate, mounting blocks are arranged on the sides, away from the positioning plate, of the side plates, two stretching plates are connected to the tops of the mounting blocks, and rectangular holes in sliding fit with the stretching plates are formed in the bottoms of the side plates; when filler and samples are added, impurities in the extraction tube can be prevented from dropping to pollute other positions by mounting the partition plate, and then after the glass test tube and the test tube rack are mounted, the extraction tube can be aligned to the top opening of the glass test tube along with descending of the positioning plate when the partition plate is taken out, when the positions of the glass test tubes do not correspond, the positioning plate can be lifted to separate the extraction tubes from the glass test tubes, so that the positions of the glass test tubes are adjusted, and subsequent accurate instillation of a to-be-detected object is facilitated.

Description

technical field

[0001] The invention relates to the technical field of antibiotic content detection, in particular to a device and method for rapidly detecting antibiotic content in camel milk or donkey milk. Background technique

[0002] Liquid chromatography is required for the detection of antibiotic content in camel milk or donkey milk. Through solid-phase extraction (SPE) or liquid-liquid extraction and other extraction methods, the camel milk or donkey milk samples were quickly and effectively pre-treated to separate a variety of antibiotic residues, and high-performance liquid chromatography was used to separate various antibiotics. Quantitative analysis of various antibiotics was carried out by the ultraviolet absorbance photometric detection method, and a reliable high performance liquid chromatography analysis method for the detection of antibiotic residues in camel or donkey milk was established.

Examples

Embodiment 1

[0037] see Figure 1-9 , in an embodiment of the present invention, a device for rapidly detecting antibiotic content in camel milk or donkey milk, comprising a base 11 and two sets of vertical plates 13 connected to the top of the base 11, and a test tube rack 14 is arranged between the two sets of vertical plates 13 , an extraction frame 15 is installed on the top of the vertical plate 13, and several extraction tubes 16 are uniformly arranged on the extraction frame 15;

[0038] A universal column connector can be installed on the extraction tube 16, and the universal column connector can be connected to a control valve, and a sample bottle or other experimental bottles can be connected on the control valve. phase extraction column.

[0039] The extraction rack 15 includes a positioning plate 26 and two groups of side plates 27 connected to the bottom of the positioning plate 26, the side plate 27 is provided with a mounting block 28 away from the positioning plate 26, and...

Embodiment 2

[0051] see Figure 10 , the difference from Embodiment 1 is that a sample bottle holder is installed on the top of the positioning plate 26, and the sample bottle holder includes a mounting plate 41 and four groups of pillars 42 connected to the bottom of the mounting plate 41, the positioning plate The top of 26 is provided with a round hole that matches with the pillar 42. The mounting plate 41 is provided with several groups of mounting holes corresponding to the position of the extraction tube 16 for mounting the sample bottle. The sample bottle holder is convenient for installation and removal, and can be installed on Sample vials or other bottles on the extraction tube 16 are further supported and fixed.

[0052] The working principle of the present invention is: when using the device for quickly detecting the antibiotic content in camel milk or donkey milk, the rear plate 17 is clamped in the first clamping plate 30 and the second clamping plate 31, and the positioning ...
