This product was developed as a universal temperature-modeled DSC to cover a wide temperature range (from -180°C to 750°C) for all common applications.
Particular emphasis was placed on an extremely stable baseline and high reproducibility.
The design allows both manual and automatic operation.
The measuring cell is designed to offer maximum mechanical and chemical resistance.
The newly developed ceramic/metal sensor delivers extremely high resolution and sensitivity.
This design offers the highest sensor sensitivity and resolution.
Thanks to our sample changer with up to 90 positions and the automatic gas dosing system, you can operate the device fully automatically at any time.
The following characteristics, among others, can be measured with a DSC: Tg, melting point, crystallization, curing, curing kinetics, onset of oxidation and heat capacity.

Application
Application example: Fructose, Glucose and Sucrose
The three processed substances (fructose, glucose and sucrose) have different melting points, which can be precisely determined using the Differential Scanning Calorimeter (DSC).
Thus, the method is used to determine unknown substances and mixtures can be recognized by molecular weight, such as fructose and glucose.
Application example: OIT “Oxidative Induction Time”/temperature
In order to predict the ageing and oxidation behavior of polymers such as PE (polyethylene, a typical packaging material), this so-called OIT test is generally used. This involves heating the polymer under the influence of oxygen using a DSC.
The application shows the OIT measurement of a common PE sample.
First, the polyethylene sample is heated to 200 °C in an argon atmosphere at a heating rate of 10 K/min.
After 3 minutes in equilibrium, the atmosphere is switched from argon to oxygen.
After a further 5 minutes, the exothermic oxidation of the sample begins. The OIT is the time that elapses between the change of gas atmosphere and the start of the oxidation reaction.
Application example: spontaneous combustion of cotton fibers
A sample of fabric material made of inorganic minerals with cotton fiber content was measured using a DSC PT 1000 to determine the auto-ignition temperature (ignition point) and heat of combustion of the cotton content.
It is important to distinguish between flash point and ignition point.
The flash point describes the temperature at which a substance can be ignited with the aid of an external ignition source such as a spark, while the auto-ignition temperature indicates the temperature at which a substance burns without an external ignition source.
The sample was heated from room temperature to 600°C at 10 K/min.
The combustion peak of the cotton components is clearly visible at around 430°C.
The enthalpy released is about 60 J/g, based on the weighed mass.
This allows the cotton content to be quantified.
The black curve shows the heat flow signal, the red curve shows the derivation of the DSC signal over the temperature in order to determine the exact start and end point of the reaction as well as the maximum of the reaction peak.
