Spectrophotometer for food endogenous toxin detection

Abstract

The invention relates to the technical field of spectrophotometers, and discloses a spectrophotometer for food endogenous toxin detection. The spectrophotometer comprises a fixed box, a signal processing display device and a servo motor, the signal processing display device is fixedly connected with the fixed box, a fixed seat is fixedly installed in the fixed box, a bottom gear is movably connected to the fixied seat in a sleeving mode, arc-shaped holes which are evenly distributed are formed in the bottom gear, and clamps are movably connected to the arc-shaped holes in the bottom gear in a clamped mode. Through the arrangement of the clamp, the clamp can clamp all solutions needing to be measured in a container from the outside and bring the solutions into a measuring instrument at a time for measurement, on one hand, the number of times of repeatedly taking and placing the container halfway is reduced, the complexity of operation is reduced, the error number of times of operation is effectively reduced, and the accuracy is improved; on the other hand, measurement fluency is guaranteed, measurement and result obtaining are completed at a time, and the measurement speed is increased.

Description

technical field [0001] The invention relates to the technical field of spectrophotometers, in particular to a spectrophotometer for detecting food endogenous toxins. Background technique [0002] The spectrophotometer uses the absorbance of light at a specific wavelength or within a certain wavelength range to conduct qualitative or quantitative analysis of the substance. It has been widely used in modern industrial production and management departments such as biology, medical materials, and environmental science. An important application, the principle is to use the polychromatic light emitted by the light source to form the monochromatic light required for measurement after passing through the monochromator. After the light passes through the test sample, part of the light is absorbed, and the light absorption value of the sample is calculated to convert it into a sample. The concentration of the sample, the absorbance value of the sample is proportional to the concentrat...

Problems solved by technology

[0003] At present, when the spectrophotometer measures the sample, it needs to measure multiple sets of standard solutions, and then establish a standard system to prepare for measuring the concentration of the sample solution. At the same time, in order to reduce the measurement error, each concentration of the standard solution needs to be measured at least Twice, and then take the average value to establish a coordinate system, but when the existing spectrophotometer is measuring, because of its single measurement optical path, the solution of the cuvette is replaced after each measurement of a standard solution of a concentration. Re-measurement, where it takes a lot of time to take out and clean the cuvette, increases the cost, affects the measurement efficiency, and the measurement process is intermittent, it is easy to make mistakes in the data, increase the measurement error, and the concentration of the standard system and the sample is only one set , the lack of reference comparison reduces the credibility
