Description
Technical Field
The present application relates generally to the field of fluid temperature control, and more particularly to a fluid temperature control system and method, and a device for controlling fluid temperature.
Background
Fluid refers to a substance capable of flowing, and is a generic term for liquid and gas.
Flow Injection Analysis (FIA) is a novel continuous Flow Analysis technique proposed in 1974 by the Danish chemist Luzika (Ruzicka J) and Hansen (Hansen E H). The technique is to inject a certain volume of sample solution into a flowing reagent solution (or water) carrier fluid with non-air space, the injected sample solution flows into a reaction coil to form a region, and the region is mixed and reacted with the reagent in the carrier fluid, and then the region enters a flow detector for measurement, analysis and recording. Since the sample solution is dispersed in the reagent carrier under strictly controlled conditions, the concentration of the analyte in the sample solution can be determined from a working curve drawn from the standard solution according to a comparative method without requiring the equilibrium state of the reaction as long as the conditions of the retention time, temperature and dispersion process in the pipe are the same in the sample solution injection method.
In water quality and soil analysis, a Flow Injection Analysis (FIA) method is often used to determine the content of ammonia nitrogen, total phosphorus, potassium permanganate index, and the like. Some of the reactions need to be controlled at a certain temperature and a certain reaction time needs to be kept, so that a device capable of controlling the temperature of the fluid needs to be designed.
