Introduction
Differential scanning calorimetry (thermal flow DSC) is a classic thermal analysis method for thermal effects at controlled program temperatures. It is used in research and development, process optimization, quality inspection, quality control and failure analysis in various materials and chemical fields today. Various occasions have been widely used. Using the DSC method, we can study the phase transition of inorganic materials, the melting of polymer materials, the crystallization process, the polymorphism of drugs, and the solid / liquid phase ratio of foods such as oils and fats.
Measure physical and chemical changes related to heat, such as glass transition temperature, melting point, melting temperature, heat of crystallization and crystallization, heat of phase transition reaction, product thermal stability, curing / crosslinking, oxidation induction period, etc. Features
1. Heat flow differential scanning calorimeter has good repeatability and high accuracy, and is especially suitable for accurate measurement of specific heat.
2. Independently developed constant temperature controller, constant temperature gas chromatography, mass spectrometry connector, and constant temperature zone can fully guarantee the secondary detection of tar and various reaction gases.
