Abstract

The invention relates to a small temperature difference measuring device, in which plate-shaped and sheet-shaped thermal sensors are employed. The device includes a twin thermal sensor, a constant temperature heat sink, a temperature sensing chamber, a heat-insulation supporter, a heat-insulation press cap, a flow-in channel and a flow-out channel. One side end surface of the thermal sensor is finely contacted with the constant temperature heat sink while the temperature sensing chamber is formed on the other side end surface. The temperature sensing chamber is connected to the flow-in channel and the flow-out channel, so that a liquid flows in from the bottom and flows out from the top. The device has good thermal stability in entire structure and arrangement, allows convenient combination, has simple structure and good compactness, is high in automation degree, can achieve reference measurement, can eliminate non-specific thermal disturbance, has high sensitivity, has advantages in application of on-site analysis and measurement, and can be applied to the fields of various calorimetric analysis and calorimetric biosensors.

Description

technical field [0001] The invention relates to a small temperature difference measuring device, in particular to a small temperature difference measuring device using plate-shaped or sheet-shaped thermal sensors, which can be applied in various calorimetric analysis, calorimetric biosensors and other fields. Background technique [0002] The calorimetric analysis method is analyzed by testing the heat change in the biochemical reaction process. It is suitable for most biochemical reactions and is not affected by sample properties such as color, turbidity, and electrochemistry. The detection principle of the calorimetric method is simple and reliable. It has gradually become an important direction for rapid detection and development in the fields of food safety, environment, and medicine. The specificity of calorimetry can be greatly improved by combining calorimetric biosensors with biological sensitive elements such as enzymes, which has advantages in the fields of on-site...
