REMEX Fully Chinese - Language Data Analysis System

The measurement system can complete the setting and control of sampler parameters, the setting and control of analysis parameters, real - time data acquisition of chemical reaction kinetics, and curve plotting. It can choose to perform absorbance/intensity measurement. In the repeated measurement state, it can perform kinetic curve tests such as cumulative superposition and average superposition synchronously with the sampling system.

Measurement and processing of measured spectrogram data: The value at any point of the measured spectrogram can be read. The effective area can be set for the waveforms at any two points of the measured spectrogram, and the area, peak value, valley value, and average value can be calculated. Abnormal points in the measured spectrogram can be removed one by one or in multiple points.
