Revolutionary Sensor Concept
The all new Chip DSC-sensor 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 1000°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.
New Chip-Sensor Technology
Worlds only commercial Heat Flux DSC with integrated heater and temperature sensor. Unmatched sensitivity, time constant and heating / cooling rates.
Highest sensitivity – for detection of melts and weak transitions
The innovative low mass Chip DSC sensor design enables us to offer a Heat Flux DSC sensor with unmatched response rate.
Benchmark resolution – precise separation of close lying events
The unique sensor design permits benchmark resolution and perfect separation of overlapping effects.
Unmatched cooling speed – low mass Chip Sensor
Due to the low mass of our Sensor we can achieve unmatched cooling speeds, enabling exiting new applications and a higher sample throughput.
Innovative Peltier cooling device can cool down (-30°C) from room temperature
The fast response rate of our Chip sensor allows us to offer Peltier cooler in addition to conventional LN2 or Intra-cooler options. With this feature we can achieve a temperature reduction of 30°C from room temperature. As our sensor reaches a linear heating rate after approximately 10°C one can evaluate reaction at around 5 to 10°C.

Applications on the Chip-DSC 100 are expandable by various accessories. You can use different cooling systems in combination with a sample robot. The sample robot is available in two versions with 42 or 84 positions.
The instrument has a gas tight design, different gas dosing options are available.
Peltier cooling system (0 – 600°C)
This is a Peltier cooled heat exchanger. The simple to install accessory reduces the starting temperature of the DSC-sensor to 0°C. Due to the low thermal mass of the sensor the DSC can now reach linear heating from 10°C onwards. With this starting temperature 90% of polymers can be evaluated.
Closed-loop Intracooler (-100 – 600°C)
Closed cycle refrigerated cooling system. Can cool down to -100°C. This Intracooler eliminates the need of refilling LN2 for cooling purposes.
Quench cooling system (-120 – 600 °C)
The Quench cooling accessories provide a LN2 reservoir that feeds the cooling socket for sample and sensor. This low cost system allows measurements in combination with a sample robot at temperatures down to -120 °C under defined atmospheres.
LN2 Cooling system (-150 – 600°C)
Controlled cooling system for ultra-low temperature application down to -150°C. This accessory provides the greatest flexibility and cooling capacity of all available options.
The all new Rhodium Software greatly enhances your workflow as the intuitive data handling only requires minimum parameter input.

Application example: 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 at 77°C, followed by a recrystallization of the amorphous parts at 170°C and a melting peak at 295°C.
