Problems solved by technology

Previously, due to technical reasons, no instrument had the ability to simultaneously measure temperature, visible light spectrum, and electrochemical titration data, which could not meet the requirements of synchronous measurement data obtained by different methods in chemical analysis. The disadvantages are: 1) Due to the inconsistency of the measurement objects, the matrix and measurement conditions of each experiment are different in separate experiments, so the data of each chemical reaction are also different, and then compared based on different experimental data During the analysis, there will be errors in the obtained chemical reaction information; 2) The small sample size cannot meet the sample requirements of multiple individual experiments, and multiple individual experiments also increase the experimental steps, prolong the experimental time, and affect the experimental process
