Abstract

The invention relates to a small temperature difference measuring apparatus which uses column-shaped, bead-shaped and spherical sensors. The small temperature difference measuring apparatus is composed of a thermal sensor, a thermal insulation plug, a temperature sensing cavity, a thermal insulation hermetic bolt, a hermetic gasket, a clamping cap, a supporting body, a flow-in channel and a flow-out channel. The thermal sensor is disposed inside the temperature sensing cavity which is connected to the flow-in channel and the flow-out channel. The apparatus herein has the characteristics of excellent thermal stability in terms of entire structure and arrangement, easy combination, simple structure, excellent compactness, high automation, reference measurement, elimination of non-specific thermal interference, and high sensitivity. The apparatus can be applied to on-site analysis and tests, and can be applied to the fields of all kinds of thermometric analysis and thermometric bio-sensors.

Description

technical field [0001] The invention relates to a small temperature difference measuring device, especially a small temperature difference measuring device using columnar, bead and spherical thermal sensors, which can be applied in various calorimetric analysis, calorimetric biosensor 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 rapid ...
