Quench cooling system (-180 – 600°C)
Our quench cooling accessories consist of an open cooling container that envelops the sensor and sample. Depending on the coolant used, such as dry ice or LN2, the sample temperature can be lowered to as low as -180 °C. Please note that this system does not support controlled gas atmospheres during measurements, as it may lead to sample outgassing.

Applications
Application: Rapid cooling rates without active cooling
The LINSEIS Chip-DSC offers the capability of achieving exceptionally fast ballistic cooling rates without the requirement for any active cooling equipment. This is made possible by the low thermal mass and innovative sensor design. Notably, it allows for cooling rates of up to 500 K/min from 400°C onwards. Even cooling down to 100°C can be accomplished with impressive rates of up to 90 K/min. Remarkably, a cooling process from 400°C to 30°C can be achieved in just 4 minutes through ballistic cooling alone, without the need for additional cooling devices.
Throughout this cooling segment, your data signal can continue to be evaluated without any loss of sensitivity or accuracy.
Application: Measurement of PET granulate
The analysis of polymers is a fundamental application of DSC, particularly when investigating phenomena like glass transitions, melting, and crystallization points, which can be challenging to detect. The new LINSEIS Chip-DSC excels in delivering high resolution and sensitivity, making it an ideal instrument for precisely this type of analysis.
For instance, consider the case of PET (Polyethylene Terephthalate) granulate. In this experiment, the PET granulate was subjected to heating, followed by rapid cooling to preserve its amorphous state. Subsequently, it was analyzed using the Chip-DSC with a linear heating rate of 50 K/min. The resulting curve exhibits a noticeable glass transition around 80°C, followed by a cold crystallization of the amorphous portions beginning around 148°C, and finally, a distinct melting peak at 230°C. This demonstrates the Chip-DSC’s effectiveness in characterizing the thermal properties of polymers, such as PET granulate.
Application: Highly energetic materials
Highly energetic materials find various applications in airbags, propulsion systems, blasting materials, and more. When working with such materials in any DSC instrument, there is a potential risk of damaging the sensor and even the furnace. However, the Chip-DSC offers a distinct advantage in this regard.
In the Chip-DSC, the chip, which integrates the sensor and furnace, can be easily replaced by the operator at a low cost and within a short timeframe. In the event of instrument damage, this results in a drastic reduction in instrument downtime. Sensor replacement requires just a few seconds, and calibration can be completed in less than half an hour. As an illustration, the provided example depicts the DSC diagram of a 2.8 mg sample of an airbag igniter.
This highlights the Chip-DSC’s suitability for handling highly energetic materials while minimizing operational disruptions in case of damage or maintenance needs.
Application: Rapid Heating Rates
The Chip-DSC excels at achieving exceptionally high heating rates, with capabilities of up to 1000 K/min. Even at these rapid heating rates, the reproducibility of the melting enthalpy remains excellent. An example illustrates this by showcasing the measurement of the melting point of Indium using various heating rates, including 5 K/min, 50 K/min, 100 K/min, 200 K/min, 300 K/min, and 500 K/min.
This means that a comprehensive analysis, encompassing both heating and cooling phases, can be completed in just 10 minutes without the necessity for additional cooling devices. The Chip-DSC’s capacity for rapid and reliable thermal analysis is exemplified in its ability to efficiently handle such high heating rates.
Application: Thermochromism
In traditional DSC instruments, the sample cannot be visually observed during the measurement process, which limits the potential insights that can be gained (such as the formation of bubbles, release of fumes, or changes in color). The provided graphic illustrates an instance of a thermochromic material undergoing an endothermic phase transition at 160°C. Notably, the different phases exhibit distinct colors, and the transition from red to yellow can be observed through the transparent cover.
To enhance the observation and documentation of such visual changes, the Chip-DSC offers a camera option for recording images. This feature allows researchers to capture and analyze additional information beyond the conventional DSC data, providing a more comprehensive understanding of thermochromic materials and their behavior during thermal transitions.
Application: Cp Determination
The measurement presented here demonstrates the modulated measurement of heat capacity (Cp) for sapphire, conducted at a heating rate of 10 K/min with an amplitude of 3 K. This method takes advantage of the rapid temperature changes and the amplitude variation induced by the sample’s heat capacity. This approach results in a high-quality signal that enables the accurate determination of heat capacity with an error margin of only 3.5%. This level of precision surpasses the capabilities of most conventional commercial DSC devices.
The use of modulated techniques in Chip-DSC, as exemplified in this measurement, offers a more accurate and refined method for determining heat capacity, providing researchers with enhanced data quality and insights in their studies.
