Differential Scanning Calorimeter - QT-DSC6 Series
The Differential Scanning Calorimeter - QT-DSC6 Series is a compact and low-cost thermal analysis instrument. Differential Scanning Calorimeter - QT-DSC6 Series have a vast number of industrial applications, particularly in the quality control of engineering thermoplastics. For example, calorimeters can determine:
- Oxidation induction time of polyethylene
- Curing percentage of epoxy
- Anti-oxide of lubricant
- Enthalpy change of material
- Glass transition temperature
- Extrapolated onset temperature
- Melting point for crystalline polymer
The Differential Scanning Calorimeter - QT-DSC6 Series uses a thermo-analytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Thermal analysis is based upon the detection of changes in the heat content (enthalpy) or the specific heat of a sample.
Applying this technique, the sample to be measured and the reference sample are placed inside a crucible, which is then placed inside the measurement cell (furnace) of the DSC system. By applying a controlled temperature program (isothermal, heating, or cooling at constant rates), caloric changes can be characterized.
Two Differential Scanning Calorimeter - QT-DSC6 Series models (Differential Scanning Calorimeter - QT-DSC6 and Differential Scanning Calorimeter - QT-DSC-6A) are available, featuring platinum electric resistance in the temperature controller, which ensures accuracy of the constant temperature to within 0.1°C. The QT-DSC-A1 model is used primarily for determining the oxidation induction time of polyethylene, the curing percentage of epoxy, and the anti-oxide of lubricants, whereas the A2 model is ideally suited for determining the enthalpy change of material and partial enthalpy change, glass transition temperature, extrapolated onset temperature and melting point for crystalline polymer, quality control of engineering thermoplastics, polyethylene/polypropylene blend and copolymer, etc.
The main advantages of this analytical technique is its rapid analyses, easy handling, and its importance in research development and quality control. The QT series differential scanning calorimeter consists of the heating furnace, host, μV amplifier, A/D converter, the μ V-mW energy converter software, the data sampling system, optional computer, and printer.
