An automatic analyzer and analysis method for reducing sugar and water-soluble total sugar content

Abstract

The invention relates to an automatic analyzer and a determination method for determining the content of reducing sugars and water-soluble total sugars, including a sampling device and a color detection device; the sampling device includes an automatic sampler, a first peristaltic pump, and the first The peristaltic pump is provided with a first pump tube, the injection needle of the automatic sampler is connected to the F port of the multi-way valve through the first pump tube, and the A port of the multi-way valve is connected to the waste liquid tank, and the There is a first back pressure regulator. The color detection device includes a second peristaltic pump, and the second peristaltic pump is provided with a second pump tube, a third pump tube, a fourth pump tube, a fifth pump tube, a sixth pump tube, and a seventh pump tube , the two ends of the sampling loop are connected to the B port and the E port of the multi-way valve, the D port of the multi-way valve is connected to the carrier solution through the second pump tube, and the multi-way valve’s Port C is sequentially connected with the first three-way, the online heating and digestion module, the second three-way, the first weaving reactor, the third three-way, the fourth three-way, the online heating and color development module, the fifth three-way, the second Braided reactors, flow cells, detectors, data link cables, and computer processing systems. The invention can continuously and automatically test samples, and the test is accurate and fast.

Description

technical field [0001] The invention relates to a fully automatic flow injection analyzer, in particular to an automatic analyzer for reducing sugar and water-soluble total sugar content and an analysis method thereof. Background technique [0002] At present, the determination of reducing sugar and water-soluble total sugar content in food, plants and other substances mostly relies on manual operation, the steps are cumbersome, human error is large, precision is poor, test speed is slow, and toxic reagents may cause damage to operators . At present, reducing sugar can be determined by high performance liquid chromatography, but the content of total water-soluble sugar cannot be directly determined, and the instrument is expensive and the test speed is slow. At present, there is a commercial bubble gap continuous flow analyzer on the market, which can directly measure the content of reducing sugar and water-soluble total sugar, but it needs to have an additional bubble addi...

[0002] At present, the determination of reducing sugar and water-soluble total sugar content in food, plants and other substances mostly relies on manual operation, the steps are cumbersome, human error is large, precision is poor, test speed is slow, and toxic reagents may cause damage to operators

At present, high performance liquid chromatography can be used to measure reducing sugar, but it cannot directly measure the content of water-soluble total sugar, and the instrument is expensive and the test speed is slow

At present, there is a commercial bubble gap continuous flow analyzer on the market, which can directly measure the content of reducing sugar and water-soluble total sugar, but it needs to have an additional bubble adding device. It is easy to enter a stable state, and it is difficult for analysts to master its operation
