DSC-600C

Differential Scanning Calorimeter

Product Introduction

Instrument Overview

Differential scanning calorimetry (DSC, also known as thermal flow DSC) is a classical thermal analysis technique for measuring thermal effects under controlled programmed temperature conditions. It has been widely adopted in a broad range of applications across the fields of materials science and chemistry—including research and development, process optimization, quality inspection and control, as well as failure analysis. Using DSC, researchers can investigate phase transitions in inorganic materials, the melting and crystallization processes in polymer materials, the polymorphic behavior of pharmaceuticals, and the solid/liquid phase composition of foods such as fats and oils.

Instrument Purpose

Measuring physical and chemical changes related to heat, such as the glass transition temperature, melting point, melting temperature, crystallization and crystallization heat, phase transition reaction heat, product thermal stability, curing/crosslinking, oxidation induction period, specific heat capacity, etc.

Main Features

u The integrated system design minimizes signal loss and interference, significantly enhances signal sensitivity and resolution, and enables the acquisition of a more stable baseline.

u Equipped with an imported high-frequency core control processor, it delivers faster computational processing speeds and more efficient control.

u The use of imported high-sensitivity sensors effectively enhances the sensitivity and accuracy of the DSC signal.

u Independent atmosphere control can be intelligently configured via software; the instrument automatically switches between different gas delivery systems, enhancing experimental efficiency.

u Both the lower-level and upper-level computers of the equipment system feature a multi-point temperature calibration function, catering to the requirements of various experimental scenarios and thereby enhancing the accuracy of temperature measurements.

u The device offers two optional experimental modes – FTC and STC – providing more intuitive and flexible temperature control that meets the diverse experimental requirements across various application scenarios. It ensures more precise temperature regulation during the experimental process and more efficient analysis of sensor signals.

u The full-temperature control system employs an optimized adaptive dynamic PID algorithm, which significantly mitigates the drawback of traditional PID algorithms requiring manual tuning and enhances the robustness of the dual-mode temperature control system.

u The 12-stage programmable temperature control feature enables greater diversity in experimental approaches.

u The sensor signal sampling frequency can be set between 1–10 Hz, offering greater flexibility in experimental methodology and enhanced data control.

u Two independent temperature sensors allow for simultaneous measurement of both the furnace temperature and the sample temperature.

u The equipment system can be used to conduct experiments on materials involving heating, cooling, or isothermal processes.

u The instrument utilizes USB bidirectional communication and supports self-recovery connectivity. Its software features an intelligent design, including a baseline subtraction function and automatic graph plotting during the experimental process. It also enables intelligent processing of various data, such as calculation of enthalpy, glass transition temperature, oxidation induction time, melting point of substances, and crystallization behavior, among others.
