Differential Scanning Calorimetry

Linseis Differential Scanning Calorimetry

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

The Differential Scanning Calorimetry (DSC) is the most popular measurement thechnique 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.

Because 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 controlwith with our DSC PT1000, DSC PT1000 HiRes and PT1600 Series in a temperature range from -180°C to 1750°C.

Differential Scanning Calorimetry

The instrument is 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 point, crystallinity, reaction enthalpy, thermal stability, oxidation stability, aging, purity, phase transformation, eutectics, polymorphs, product identification, curing and cure kinetics.

The LINSEIS Differential Scanning Calorimeter (DSC) have a unsurpassed performance:
  • Revolutionary Sensor Design – Combined Heat Flux & Power Compensation in one Sensor
  • Unsurpassed sensitivity – for detection of melts and weak transitions
  • Benchmark resolution – precise separation of close lying events
  • Reliable Automation – up to 64 position autosampler
  • Widest temperature range – from -180 °C to 750 °C in one measurement (DSC PT1000) 

Our instruments operate in agreement with national and international standards such as: ASTM C 351, D 3417, D 3418, D 3895, D 4565, E 793, E 794, DIN 51004, 51007, 53765, 65467, DIN EN 728, ISO 10837, 11357, 11409.

LINSEIS DSC PT1000 - Differential Scanning Calorimeter:
Differential Scanning Calorimetry (DSC) - very robust - highest precision sensor

Differential Scanning Calorimeter DSC 1000

This product was developed to provide a general purpose TM - DSC with a broad temperature range (-150 – 725°C) for all common applications. Furthermore emphasis was placed on an extremely stable baseline and high reproducibility. The design allows manual and automatic operation. The conception of the cell guarantees maximum mechanical and chemical resistance. The 120 thermocouple sensor MR12 provides highest resolution and outstanding sensitivity

LINSEIS DSC – 1000 HiRes - Differential Scanning Calorimeter:

Research grade TM - DSC with unsurpassed HR24 Sensor comprising 240 thermocouples and a dual detector arrangement, combining the advantages of heat flux and power compensation technology into one integrated sensor arrangement. This design provides the highest sensitivity and resolution in the market, outperforming all competitive designs by a magnitude. Furthermore the instrument allows full automation due to its 64 position autosampler, automatic gas dosing system and the optional vacuum tight design. The broad temperature range (-180 up to 750°C) ensures that even most demanding applications can be analyzed.

DSC PT1600 - Differential Scanning Calorimeter:
High temperature Differential Scanning Calorimetry (DSC) up to 1750°C

Differential Scanning Calorimeter DSC 1600

Differential Scanning Calorimetry (DSC) is the most common thermal analysis method due to its wide range of information provided. The LINSEIS high temperature DSC PT1600 (HDSC/DTA) is designed to deliver highest calorimetric sensitivity, short time constants and a condensation free sample chamber. These features guarantee superior resolution and baseline stability over the entire instrument lifetime. This provides an indispensable tool for material development, R&D and quality control.

The modular concept of the HDSC and DTA systems allows the use of different furnaces with a temperature range from -150°C up to 1750°C. The vacuum tight design enables quantitative enthalpy and Cp (Specific Heat) determination under the cleanest atmospheres and under vacuum of 10E-5mbar. The systems can be upgraded with an optional sample robot and coupled to a MS or FTIR.
