Q1: What is the temperature range of this DSC instrument, and what types of materials is it suitable for?
A1: This DSC instrument features a wide temperature range from -150°C to 600°C. It is suitable for thermal performance testing of various materials, including polymers, metals, and composite materials, covering common testing scenarios such as glass transition temperature (Tg), melting point (Tm), and crystallization temperature (Tc) measurements.
Q2: What is the adjustable range of heating/cooling rates for the DSC, and how is the rate stability ensured?
A2: The instrument supports a heating/cooling rate range of 0.1°C/min to 80°C/min, with stepless adjustment to meet both slow and rapid thermal analysis requirements. Equipped with a high-precision PID temperature control system and a high-efficiency furnace structure, it ensures rate stability within ±0.5% of the set value, effectively guaranteeing the repeatability of test data.
Q3: What is the temperature accuracy and resolution of this DSC instrument?
A3: The instrument achieves a temperature accuracy of ±0.1°C across the full temperature range, and a temperature resolution of 0.01°C. This high-precision performance ensures accurate capture of subtle thermal events (such as weak exothermic/endothermic peaks), providing reliable data support for material research and quality control.
Q4: What types of sample pans does the DSC support, and what is the maximum sample weight it can accommodate?
A4: The DSC is compatible with multiple standard sample pan types, including aluminum pans (for general-purpose testing), stainless steel pans (for high-pressure scenarios), and ceramic pans (for corrosion-resistant requirements). It supports both solid and liquid samples, with a maximum sample weight of 100mg per test, balancing testing sensitivity and sample utilization.
Q5: Does this DSC instrument support atmosphere control, and what are the key parameters of its atmosphere system?
A5: Yes. The instrument is equipped with a fully automated atmosphere control system, supporting inert atmospheres (nitrogen, argon), oxidizing atmospheres (air, oxygen), and vacuum conditions (down to 10⁻³ Pa). The gas flow rate is adjustable from 10 mL/min to 200 mL/min with an accuracy of ±1 mL/min, and the atmosphere switching time is less than 30 seconds, meeting the requirements of thermal analysis under different environmental conditions.
