Technology

High Sensitivity

High-performance, oxidation-resistant substrate sensors deliver baseline drift ≤100 μW and inter-baseline variation ≤0.04 mW. Exceptional baseline stability provides a reliable foundation for precise heat flow measurement, enabling accurate capture of even weak thermal effects and improving the reliability and reproducibility of thermal analysis results.

Stable & Repeatable

Phase transition temperature precision ±0.02 °C (In standard), enthalpy measurement accuracy ±0.08% (In). Feedforward intelligent prediction algorithms combined with high-precision atmosphere flow control ensure stable baselines, rapid response, and excellent signal-to-noise ratio.

Smart Automation

A 60-position autosampler supports flexible partitioning of sample and reference zones, with an intelligent robotic arm automatically handling loading, placement, capping, and waste disposal. The system enables 24-hour continuous operation, significantly increasing throughput while reducing manual intervention.

Wide Temperature Range

An integrated silver furnace delivers uniform heat conduction and stable temperature fields, covering from room temperature to 700 °C with fast heating/cooling response and minimal thermal lag. An optional mechanical refrigeration module extends the lower limit to −90 °C for low-temperature applications such as polymer Tg, pharmaceutical cold crystallization, and food stability testing.

Modular Design

Optional modules include autosamplers, low-temperature cooling units, and various detection accessories for flexible expansion according to experimental needs. Multiple crucible materials and geometries are available, with an optional crucible press to optimize sample–crucible contact, improving peak quality and data repeatability.

FAQ

【Q】What is the working principle of DSC?

【A】A differential scanning calorimeter (DSC) is a thermal analysis instrument used to measure the relationship between temperature and heat flow during thermal transitions in a material. Its working principle is as follows: under programmed temperature control, the sample and reference are heated or cooled simultaneously at the same rate. When the sample undergoes a phase transition or another thermal event, heat is absorbed or released, resulting in a temperature difference between the sample and the reference. This difference is detected by a thermocouple or a resistance temperature detector (RTD) and converted into a heat flow signal. By analyzing variations in this signal, the thermodynamic properties of the sample can be determined.

【Q】What materials can DSC analyze?

【A】DSC is widely used across polymers, pharmaceuticals, food, coatings, metals, and composites. Common samples include plastics, rubbers, resins, drugs, fats and oils, and metal alloys — for determining glass transition, melting/crystallization, curing, oxidation stability, and specific heat capacity.

【Q】What sample size is required for DSC testing?

【A】The sample mass is typically no more than 10 mg, depending on the material type and testing purpose. Crucibles are available in various materials and sizes to accommodate different sample types, with compatible pressing tools required for different crucible types. A sample press can optimize sample packing and contact within the crucible, thereby improving peak resolution and data repeatability.

【Q】What experimental modes and data analysis capabilities does DSC support?

【A】It supports multiple experimental modes, including isothermal mode, scanning mode, and specific heat capacity measurement. PyroSwift software features built-in baseline correction, peak analysis, automatic glass transition calculation, specific heat capacity determination, multi-curve overlay comparison, and basic thermal kinetics analysis, meeting data processing needs across the entire workflow, from routine quality control to R&D characterization.
