Differential Calorimeter Scanner

Product Introduction

DS-520 Differential Scanning Calorimeter (DSC) is a precision instrument used for thermal analysis, primarily for studying the changes in thermal properties of materials under controlled temperature programs.

Core Functions and Working Principles

By measuring the difference in heat absorbed or released by the sample and a reference material during temperature changes, it analyzes the thermal transition behavior of materials (such as melting, crystallization, phase transition, glass transition, oxidation induction period, etc.).

The sample and reference material are placed in a temperature-controlled furnace.  The temperature is increased or decreased according to a set program. A thermocouple detects the temperature difference between the two, and the heat flow change curve of the sample (DSC curve) is calculated and recorded, thereby inferring the thermal performance parameters of the material (such as melting enthalpy, crystallization enthalpy, transition temperature, etc.).

Application

Materials Science: Studying the thermal stability, phase transition behavior, and processing optimization of polymer materials (plastics, rubber, resins, etc.), metal alloys, ceramics, and composite materials.

Medicine and Biology: Analyzing the melting point, crystal form transformation, and thermal stability of drugs, and evaluating the compatibility of pharmaceutical formulations.

Food Industry: Determining the thermal stability, water activity, and fat oxidation of food components, and optimizing food processing and storage conditions.

Chemical Engineering: Studying catalyst activity, reaction kinetics, and polymer degradation processes.

Features

1.     High Precision: Can accurately measure minute heat changes (typically with an accuracy of ±0.1%), suitable for trace sample analysis.

2.     Automation: Equipped with a touch screen display (as shown in the image), supporting programmed temperature control and real-time data acquisition and analysis.

3.     Multifunctional: Some models can be expanded with combined techniques (such as coupling with a thermogravimetric analyzer (TGA)), simultaneously monitoring mass changes and heat flow changes to enhance the analytical dimension.
