DSC Philippines | Hitachi NEXTA DSC Series Differential Scanning Calorimeter
Features
World-class baseline repeatability
Both NEXTA DSC600 and DSC200 use an advanced heat-flow design in the sensor. This allows the heat from the heat sink transferred evenly to the sample and the reference, resulting in the high baseline stability. Together with a furnace built with a low-heat-capacity three-layered insulation design, this allows the NEXTA DSC achieves world-class baseline repeatability and stability.
World-class sensitivity
The NEXTA DSC600 has a proprietary thermopile-type DSC sensor. By using differential scanning calorimetry (DSC signal) temperature sensor thermocouples connected in series and multiplexed, the NEXTA DSCs achieve a high sensitivity of 0.1 µW or lower, enabling measurement of even smaller samples.
Wider temperature range for Real View® DSC
The Real View Sample Observation Unit has a built-in two-megapixel high-resolution camera that supports visual observation of the sample. The viewport (observation window) has a heating mechanism that extends the measurement range from the conventionally observable range of room temperature and above down to the low temperature of -50°C. This enables the user to observe processes such as the crystallization and the glass transition, for example, of samples at low temperatures. This offers a unique capability for understanding material behavior.
Specific heat capacity determination by temperature modulated DSC method
The reversing heat flow (which shows glass transition and melting) and non-reversing heat flow (which shows enthalpy relaxation, curing, evaporation, decomposition, etc) are obtained from a modulated DSC measurement. This is useful when these transitions or reactions overlap or stress relief obscures a transition. The modulated DSC method can also be used for determining the specific heat capacity (Cp), which simplifies measuring Cp.
