A device for heating chromatographic plates with low-temperature hot water

Abstract

The invention provides a device for heating a chromatographic plate with low-temperature hot water, which includes a water heater, the water heater includes a hot water outlet, and the hot water outlet is connected to one or more heat utilization devices through pipelines, and the water is heated in the heat utilization device After exchanging heat, it circulates back to the water heater, the at least one heat utilization device includes a flat tube, the upper part of the flat tube is arranged with a device to be heated, and the temperature of the hot water at the hot water outlet is 30-40 degrees Celsius. The present invention is heated by setting hot water, because the hot water can realize low-temperature heating, and the temperature and the flow rate of the hot water can also be controlled during the heating process, thereby ensuring the heating quality and maintaining and controlling the volatilization stability of the chromatographic plate adhesive.

Description

technical field [0001] The invention relates to a hot water heating device, in particular to a steam heating device for low-temperature hot water. Background technique [0002] Heat pipe technology is a heat transfer element called "heat pipe" invented by George Grover of Los Alamos National Laboratory in the United States in 1963. It makes full use of the principle of heat conduction and phase change medium. The rapid heat transfer properties of the heat pipe quickly transfer the heat of the heating object to the heat source, and its thermal conductivity exceeds that of any known metal. [0003] Heat pipe technology was widely used in aerospace, military and other industries before. Since it was introduced into the radiator manufacturing industry, people have changed the traditional radiator design ideas and got rid of the single heat dissipation mode that only relies on high air volume motors to obtain better heat dissipation. The use of heat pipe technology enables the r...

Problems solved by technology

[0005] Counterfeit and inferior drugs and illegally added chemical drugs frequently appear in my country's drug market, and the product quality is unstable, seriously affecting the drug safety of the people

The further improvement of analysis and detection technology is one of the main problems that need to be solved urgently. Traditional technology is difficult to achieve instant and rapid quality evaluation of drugs. Therefore, there is an urgent need to innovate key technologies for rapid inspection of food, drugs, and cosmetics.

At present, commonly used methods for rapid detection include TLC (thin layer chromatography), HPLC, LC-MS, etc. Among them, the TLC method is simple to operate, low in detection cost, and easy to promote at the grassroots level, but its separation efficiency is low, and there are often false positive interferences ; HPLC method is sensitive and accurate, but the analysis period is long, which cannot meet the needs of rapid detection; LC-MS method has strong specificity, high sensitivity, and accurate qualitative, but its detection cost is high, and it is not suitable for on-site inspection of rapid detection

Moreover, in the laboratory, the above method is often used to identify illegally added chemical drugs through chemical reaction, large-scale instrument detection and other methods. The steps are cumbersome and cannot be applied in the field.

[0006] In the prior art, the phenomenon of counterfeit and inferior products and illegal addition of chemical drugs in my country's food, drug and cosmetics markets is frequent, the quality of products is unstable, and the amount and composition of illegal additions are chaotic, which seriously affects the health and safety of the people.

The further improvement of analysis and detection technology is one of the main problems that need to be solved urgently. Traditional technology is difficult to achieve instant and rapid quality evaluation of samples. Therefore, there is an urgent need for innovative and rapid detection of key technologies

At present, the commonly used method for rapid detection is TLC (thin-layer chromatography), but the above-mentioned monitoring method quickly volatilizes the residual developing agent, which is conducive to thin-layer chromatography imaging, and then sprays glue on the chromatographic plate, which needs to be carried out after spraying. Heating at low temperature will volatilize the solvent in the glue, for example, around 35 degrees Celsius. In the prior art, infrared heating is generally used, or a hair dryer is used. The temperature is not easy to control, and resources are wasted and inefficiency.
