DSC PT 1000

very robust – highest precision sensor


On point

Our product was meticulously developed to serve as a versatile TM-DSC (Thermomechanical-Differential Scanning Calorimetry) solution with an extensive temperature range spanning from -180°C to 600°C, catering to a wide range of common applications. We placed a strong emphasis on achieving an exceptionally stable baseline and high levels of reproducibility. Our design offers both manual and automatic operation options, providing flexibility to users. The cell’s conception prioritizes maximum mechanical and chemical resistance, ensuring durability.

The heart of any DSC instrument lies in its sensor, and we make no compromises in this regard. Historically, achieving both the highest resolution and sensitivity in a single sensor has been a challenge. However, the revolutionary HiperRes® Sensor line’s innovative design now makes this possible. The Ceramic/Metal Sensor delivers outstanding resolution paired with superior reproducibility, enabling the detection of even the smallest thermal effects.

The metal-ceramic sensor structure guarantees the shortest possible time constants, enabling the separation of overlapping effects across the entire temperature range. In contrast to competing metal sensors, the ceramic design remains oxidation-resistant, allowing for continuous use throughout the full temperature range without experiencing aging effects.

Applications example: Fructose, Glucose and Saccharose

Fructose, Glucose, and Saccharose, when subjected to analysis, reveal distinct melting points. Differential Scanning Calorimetry (DSC) offers precise methods for determining these melting points. This analytical technique is commonly employed to identify unknown substances, and it’s particularly effective in distinguishing mixtures with similar molecular weights, such as Fructose and Glucose.

Applications example: Thermoplasts

Polyethylene terephthalate (PET) exhibits a distinctive endothermic glass transition point at approximately 76.9°C, a notable characteristic for partially crystalline thermoplastics. The correlation between the exothermic cold crystallization occurring at 131.0°C and the subsequent endothermic melting peak serves as an indicator of the material’s degree of crystallization. In the case of PET, the crystalline portion is relatively minimal, contributing to the material’s excellent transparency.

Application example: OIT “Oxidative Induction Time”/ Temperatur

The polyethylene sample is first heated to 200°C within an argon atmosphere, utilizing a heating rate of 10 K/min. Following a 3-minute period at thermal equilibrium, the environmental conditions shift from argon to oxygen. After an additional 5 minutes, the exothermic oxidation process of the sample initiates.

Application example: Auto-ignition of cotton fibers

To determine the auto-ignition temperature (ignition point) and heat of combustion of the cotton content in a sample that also contains inorganic minerals, DSC PT 1000 was employed. It’s essential to differentiate between the flash point and the ignition point.

The flash point refers to the temperature at which a substance ignites when exposed to an external ignition source, such as a spark. On the other hand, the auto-ignition temperature is the temperature at which a substance spontaneously ignites without the need for an external ignition source.

In this experiment, a sample of cotton fiber, inclusive of inorganic minerals, was heated from room temperature to 600°C at a rate of 10 K/min using the Linseis DSC PT 1000. The results are depicted in the graph, illustrating the heat flux signal (in black) and its derivative (in blue) as the cotton mass underwent heating. Oxidation of the cotton mass commenced at 435.4°C and was entirely combusted by 461.6°C.

The total energy released during the combustion reaction of the cotton mass was calculated as 60 J/g, determined by assessing the area under the heat flux peak using the Linseis evaluation software package.
