Description

Technical Field

[0001] The present invention relates to the technical field of purity detection, and in particular to a device and method for detecting the purity of emamectin benzoate. Background Art

[0002] In the process of purity detection of emamectin benzoate, it is often necessary to use a liquid chromatograph, which is an instrument that uses the difference in the distribution ratio of the mixture between liquid and solid or between two immiscible liquids to separate the mixture first and then analyze and identify it. It is widely used in biochemistry, food analysis, medical research, environmental analysis, inorganic analysis and other occasions, and has good use effect.

[0003] At present, the mainstream liquid chromatography technology framework is mainly composed of core components such as high-pressure infusion pumps, precision injection systems, temperature control systems, high-efficiency chromatographic columns, high-sensitivity detectors, and precise signal recording systems. Both temperature and uniformity can affect the results of the analysis, thereby affecting the separation performance of the column and the viscosity of the mobile phase. Therefore, ensuring a constant column temperature is very important for the accuracy and repeatability of the results. In addition to the column temperature control system, the initial temperature of the sample and mobile phase entering from the outside will also affect the control stability of the column temperature. However, when the existing liquid chromatograph is in use, the sample and mobile phase entering from the outside are not heated, which leads to certain errors in the measurement process of the liquid chromatograph, reducing the accuracy of the liquid chromatograph measurement.

[0004] In addition to the core link of column temperature control, the initial temperature of the externally introduced sample and mobile phase also has an important impact on the stability of column temperature control. Unfortunately, in the routine operation of existing liquid chromatographs, the preheating of external samples and mobile phases is often neglected. This omission leads to the introduction of unnecessary errors in the measurement process, which in turn weakens the accuracy of the instrument measurement. What is more serious is that with the increase of temperature, the solubility of the gas in the solvent will decrease significantly, thereby precipitating and forming bubbles. At the same time, the reduction of pressure in the system will also become a cause of bubble generation. These bubbles will not only cause baseline fluctuations and increase in noise levels, but also seriously interfere with the clarity of the detection signal, making it difficult to accurately identify and quantitatively analyze the chromatographic peaks; moreover, they may also disrupt the normal operation of the pump, resulting in unstable flow rate fluctuations, which has a negative impact on the separation effect. Once the bubbles invade the interior of the chromatographic column, they will change the flow rate distribution of the mobile phase in the column, resulting in a decrease in column efficiency, which seriously affects the separation effect of the sample.

[0005] In view of the above problems, the present invention document proposes a device and method for detecting the purity of emamectin benzoate. Summary of the invention

An inner sleeve 2043 is arranged on the outer sleeve of the polygonal shaft 2042. By setting the polygonal shaft 2042 to a polygonal structure and matching the inner opening shape of the inner sleeve 2043 with the polygonal shaft 2042, the polygonal shaft 2042 can be rotated stably. The rotation of the side shaft 2042 can drive the inner sleeve 2043 to rotate, and the inner sleeve 2043 can also move smoothly up and down along the polygonal shaft 2042. The outer sleeve 2044 is fixedly connected to the outside of the inner sleeve 2043. The outer sleeve 2044 is rotatably installed on the outer shell 2071 through two bearings. The outer sleeve 2044 can rotate smoothly through the bearings, so that the outer sleeve 2044 can drive the first bevel gear 2045 and the second bevel gear 2062 to stably transmit. The first bevel gear 2045 is fixedly connected to the outer sleeve 2044, and the first bevel gear 2045 is meshed with four second bevel gears 2062.

A plurality of balls 2052 are fixedly connected to the upper portion of the chassis 2051. The arrangement of the balls 2052 is the same as that of the convex balls 2076. The balls 2052 are in contact with the convex balls 2076. Since the balls 2052 have good rolling properties, when the balls 2052 are squeezed with the convex balls 2076, the friction resistance between the balls 2052 and the convex balls 2076 can be reduced, thereby improving the operation flow.

Moreover, this method is simple to operate and has low cost.
