Linseis Chip-DSC 10: Miniature-DSC with new sensor

Description

To the point

The Chip DSC 10 integrates all essential parts of the DSC, heater, sensor and electronics in a miniaturized housing. The chip arrangement consists of a heater and temperature sensor in a chemically inert ceramic arrangement with a metallic heater and temperature sensor.

This arrangement enables high reproducibility and, due to the low mass, excellent temperature control and heating rates of up to 300 K/min.
The integrated sensor is easily replaceable and available at low cost.

The integrated design of the chip sensor provides excellent raw data, allowing direct analysis without pre- or post-processing of the heat flow data.

The compact design leads to a significant reduction in production costs, which can be passed on to our customers.
The low energy consumption and unsurpassed dynamics result in the unrivaled performance of this revolutionary DSC concept.

Chip technology

The world’s only chip DSC sensor with integrated heater and heat flux sensor.
Unsurpassed heating and cooling rates and time constants.

Benchmark resolution – precise separation of overlapping events

The unique sensor design enables excellent resolution and perfect separation of overlapping effects.

Highest sensitivity – for the detection of melts and weak transitions

The innovative chip design enabled us to develop a DSC sensor with the lowest possible mass.
This makes it possible to offer a heat flow DSC with an unsurpassed response rate.

Unsurpassed cooling speed – thanks to “low mass” chip sensor

Due to the low mass of our sensor, we can achieve unsurpassed cooling speeds, resulting in new applications and higher sample throughput.

Quench cooling system (-180 – 600°C)

The quench cooling accessory provides an open cooling container that surrounds the sensor and the sample.
Depending on the coolant, the sample temperature can drop to -180 °C.
This system does not allow defined gas atmospheres during a measurement as the sample is surrounded by outgassing.

Applications

Application: Fast cooling rates without active cooling

The LINSEIS Chip DSC enables the fastest possible ballistic cooling rates without the need for an active cooler.
Due to the low thermal mass and the innovative sensor design, cooling rates of up to 500 K / min from 400 °C can be achieved.
With cooling rates of up to 90 K / min, cooling to 100 °C can even be achieved.
Cooling from 400 °C to 30 °C is possible in just 4 minutes by ballistic cooling.
Of course, the signal can still be evaluated during the cooling process and loses neither sensitivity nor accuracy.

Application: Measurement of PET pellets

The analysis of polymers is one of the main applications of chip DSC.
Physical effects such as glass transitions, melting and crystallization points are of particular interest and often very difficult to detect.
The LINSEIS chip DSC offers high resolution and sensitivity and is therefore an ideal instrument for polymer analysis.
As an example, a PET pellet was heated, cooled to freeze the amorphous state and then analyzed on the chip DSC with a linear heating rate of 50 K / 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 point at 230 °C.

Application: High-energy materials

High-energy materials are used, for example
used in airbags as propellants for explosive opening in the event of an accident.
In such analyses with DSC devices, there is a risk of damage to the sensor and furnace.
A major advantage of chip DSC is that the chip (integrating sensor and furnace) can be replaced easily and inexpensively by the operator in just a few simple steps.
In the event of damage to the measuring device, downtimes are drastically reduced.
A sensor change only takes a few seconds and calibration can be carried out in less than a quarter of an hour.
The example shows the DSC diagram of 2.8 mg airbag igniter.

Application: Fast heating rates

Extremely high heating rates of up to 1000 K / min can be achieved, while the reproducibility of the melting enthalpy remains excellent.
The example shows the melting point of indium measured at different heating rates (5 K / min; 50 K / min; 100 K / min; 200 K / min; 300 K / min and 500 K / min).
With the chip DSC, a complete analysis including heating and cooling can be performed in just 10 minutes without optional cooling equipment (ballistic cooling).

Application: Thermochromics

With classic DSC devices, the sample cannot be observed during the measurement.
However, observing the sample can provide a lot of useful information (formation of bubbles or vapors, color change, etc.).
The graph shows an example of a thermochromic material showing an endothermic phase transition at 160 °C.
The phases have different colors and the color change from red to yellow is visible through the transparent cover.
A camera option is available to take pictures.

Application: Cp determination

The following measurement shows the modulated measurement of the heat capacity of sapphire at a heating rate of 10 K / min with an amplitude of 3 K. Due to the rapidly changing temperature and the change in amplitude caused by the heat capacity of the sample, a good signal quality can be achieved, which allows an assessment of the heat capacity with an error of only 3.5%.
A significantly better result than with most DSC devices.
