Revolutionary Sensor Concept
The all new Chip-DSC 1 integrates all essential parts of DSC: furnace, sensor and electronics in a miniaturized housing. The chip-arrangement comprises the heater and temperature sensor in a chemically inert ceramic arrangement with metallic heater and temperature sensor.
This arrangement allows superior reproducibility and due to the low mass outstanding temperature control and heating rates of up to 100°C/min. The integrated sensor is easily user exchangeable and available for a low cost.
The integrated design of the chip-sensor delivers superior raw data, which enables a direct analysis without pre- or post-processing of heat flow data.
The compact construction, leads to a significant reduction in production cost which can be passed on to our customers. The low energy consumption and unrivaled dynamic response result in unsurpassed performance of this revolutionary DSC-concept.

Application: Rapid cooling rates without active cooling
The Linseis Chip-DSC allows fastest possible ballistic cooling rates without any active cooler needed. Due to the low thermal mass and innovative sensor design, cooling rates up to 200°C/min from maximum temperature to 100°C and up to 50°C/min from 100°C to room temperature are possible. Starting ballistic cooling from a 400°C isothermal segment, 50°C is reached under 3 min measurement time. Of course, the signal can still be evaluated during that cooling segment and does not lose sensitivity or accuracy.
Application: Measurement of PET granulate
The analysis of polymers is one of the main applications of DSC. Effects like glass transitions, melting and crystallization points are of interest and often very hard to detect. The new Linseis Chip-DSC provides high resolution and sensitivity, making it an ideal instrument for this kind of analysis. As an example, a PET granulate was heated, quench cooled to freeze the amorphous state and afterwards measured by Chip-DSC with a linear heating rate of 50°C/min. The curve shows a significant glass transition around 80°C, followed by a cold crystallization of the amorphous parts starting at 148°C and a melting peak at 230,6°C.
