Differential Scanning Calorimeter – DSC


Heat Flow measurements from -180°C up to 1750°C

Linseis has many years of experience in constructing Differential Scanning Calorimeter, we have been able to meet highest demands for each request from research / development and quality control in a temperature range from -180°C to 1750°C and a pressure range from vacuum up to 300 bar.

The Differential Scanning Calorimetry (DSC) is the most popular measurement technique to detect endothermic and exothermic transitions like the determination of transformation temperatures and enthalpy of solids and liquids as a function of temperature. Therefore the sample and reference are maintained at nearly the same temperature throughout the experiment and the heatflux will be measured.

The Differential Scanning Calorimeter are used to characterize polymers, pharmaceuticals, foods/biologicals, organic chemicals and inorganics.

The following interesting physical properties of materials can be measured:
  • enthalpy
  • melting energy
  • specific heat
  • glass transition
  • crystallinity
  • reaction enthalpy
  • OIT/OOT
  • thermal stability and oxidation stability
  • aging
  • purity
  • eutectics
  • polymorphs
  • thermochromism
  • curing and
  • cure kinetics

    Products


    of Differential Scanning Calorimeter

    Chip-DSC 1
    The all new Chip-DSC 1 integrates all essential parts of DSC: furnace, sensor and electronics in a miniaturized housing. The chip-arrangement comprises the heater and temperature sensor in a chemically inert ceramic arrangement with metallic heater and temperature sensor.This arrangement allows superior reproducibility and due to the low mass outstanding temperature control and heating rates of up to 100 K/min. The integrated sensor is easily user exchangeable and available for a low cost.The integrated design of the chip-sensor delivers superior raw data, which enables a direct analysis without pre- or post-processing of heat flow data.The compact construction, leads to a significant reduction in production cost which can be passed on to our customers. The low energy consumption and unrivaled dynamic response result in unsurpassed performance of this revolutionary DSC-concept.
