Soret Coefficient Measurement Device with Dynamic Temperature Control

The patent applies preliminary action by pre-heating the liquid sample before the actual measurement begins. The liquid is heated to a higher temperature initially, then the temperature gradient is applied. This preliminary heating creates a larger initial temperature difference that accelerates thermal diffusion, allowing measurable concentration changes to occur more quickly while maintaining measurement accuracy.

The patent changes the temperature parameter dynamically during the measurement process. Instead of maintaining a constant small temperature gradient throughout, the system initially applies a larger temperature difference to accelerate diffusion, then adjusts the gradient to maintain optimal measurement conditions. This parameter variation allows the system to achieve both fast measurement and high precision.

The patent segments the temperature control system into distinct functional modules: a heating unit with heating wire, a cooling unit with Peltier element, and an insulating layer. Each module performs a specific function and can be independently controlled and maintained. This segmentation simplifies the overall device structure while maintaining precise temperature control capability, as each module can be optimized separately without affecting the entire system complexity.

The temperature regulating component serves multiple functions: it can both heat and cool the liquid sample, it provides temperature stabilization during measurement, and it enables rapid temperature changes when needed. By making the temperature control system multi-functional, the patent reduces the need for separate heating and cooling devices, thereby simplifying the overall device structure while maintaining measurement precision.
