Differential Scanning Calorimeter – DSC PT1000

000

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, DSC PT1000 High Pressure and DSC PT1600 Series in a temperature range from -180°C to 1750°C and a pressure range from vacuum up to 300 bar.

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)

Measurement applications:

  • Phase transitions – Determination of melting and crystallization points as well as phase transitions by measurement of the change of enthalpy over temperature.
  • Determination of Glass Temperature – Measurement of TG with high resolution calorimetric detection
  • Measurement of specific heat CP – Determination of specific heat CP of solids and liquids with sapphire standard.
  • Enthalpy measurement of chemical reactions – Determination of endothermic and exothermic enthalpy ΔH of chemical reactions
  • Measurement of thermal / oxidative stability – Determination of OIT (Oxidation Induction Time) in various gas atmospheres and at different pressures.

Possible measurement conditions:

  • Temperature range from -150°C to 1750°C
  • Various gas atmospheres: air, nitrogen, helium, argon, getter gas, vacuum etc.
  • Pressure from 10-5 mbar to 150 bar

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:

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 – PT1000 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.

LINSEIS DSC – PT1000 High Pressure – Differential Scanning Calorimeter:

This High Pressure Differential Scanning Calorimeter (HP-DSC) is used to characterize polymers, pharmaceuticals, foods/biologicals, organic chemicals and inorganics under very high pressure of up to100 bar (High Pressure) or even 300 bar (Ultra High Pressure). Ther possible temperature range is -125°C up to 725°C. Transitions measured include Tg, melting, crystallization, curing, cure kinetics, onset of oxidation and heat capacity.
