Synchronous Thermal Analyzer SR-STA-1250

Instrument Introduction

Synchronous thermal analysis combines thermogravimetric analysis (TG) with differential thermal analysis (DTA) or differential scanning calorimetry (DSC). By using the same sample in the same measurement, TG and DTA or DSC information can be obtained synchronously. Thermogravimetric analysis (TG, TGA) is the process of observing the changes in the mass of a sample with temperature or time during heating, constant temperature, or cooling, with the aim of studying the thermal stability and composition of the material. Widely used in research and development, process optimization, and quality monitoring in various fields such as plastics, rubber, coatings, pharmaceuticals, catalysts, inorganic materials, metal materials, and composite materials.
