Features and Benefits
of DSC 5+

Innovative technology, increased performance, and a more productive DSC. The perfect solution for unbeatable DSC performance.

Patented Electrical Heat Flow Adjustment
Saves Operator Time and Ensures Excellent Measurement Accuracy

The innovative design of the MMS 1 sensor includes 2 integrated heaters. This enables the patented electrical heat flow adjustment and a sensor that can accurately self-adjust for heat flow.

During the adjustment process, the heaters provide a pulse of heat ev­ery 50 K, with the response being accurately measured by the temperature sensors. The heatflow is measured over a temperature range that is not possible with reference materials, with no sample preparation needed, and no operator bias. The result is a DSC that is always correctly adjusted over the entire temperature range.

This advanced feature allows users to save valuable time and increase productivity with the automatic instrument adjustment.

Power Compensation
Power Compensation Provides Outstanding Resolution for Separating Close-Lying Effects

In power compensation mode, the aim is to keep the temperature difference between the sample and reference sides as close to zero as possible. On the MMS DSC sensor, this is achieved by two local heaters, one below the sample side, the “sample heater” and one below the reference, the “reference heater”. When the sample heats up due to an exothermic reaction, the reference heater activates until the reference temperature equals that of the sample. When the sample side “cools” due to an endothermic reaction, the sample heater activates until the sample temperature equals that of the reference side, which follows the programmed temperature.

The amount of power introduced by the sensor heaters is very precisely measured, resulting in a heat flow signal with outstanding resolution, and excellent separation of close-lying effects.

MultiSTAR™ Sensor with 136 Thermocouples
Gives Exceptional Sensitivity for the Measurement of Weak Effects

The revolutionary MMS 1 DSC sensor, with 136 thermocouples and 2 integrated heaters for power compensation mode, provides superior performance. FlexMode™ allows the user to choose between measurement in either power compensation or heat flux mode.

The MMS 1sensor has two layers of 68 thermocouples in the MultiSTAR™ arrangement. These thermocouples measure the temperature difference of the sample (Ts) and reference positions (Tr). In heat flux mode, when Ts ≠ Tr due to an endo- or exo-thermic effect, the temperature difference between the sample and reference is related to the heat flow of the sample.

The use of power compensation combines the stability and robustness of a heat flux DSC with the short signal time constant and accuracy of the power compensation technology. This provides excellent resolution for the separation of close lying effects.

FlexMode™
Choose Power Compensation or Heat Flux Mode — for Optimal DSC Performance

The advanced DSC 5+ sensor with FlexMode™ functionality provides superior performance and allows the user to switch between modes to best suit the needs of the sample under investigation.

Power Compensation mode has a very short signal-time constant, providing excellent resolution and the ability to separate close-lying thermal effects.

Heat Flux mode has low levels of noise which provides the highest sensitivity for the detection of weak effects.

Time-Saving FlexCal™ Adjustment
Guarantees Accurate Results Under All Measurement Conditions

FlexCalis a unique tool that reduces the time needed for in­strument adjustment by storing adjustment parameters for each combination of module, crucible, and gas type in a database. Depending on the method, the module applies the correct ad­justment parameters, even if the gas type is switched during the measurement. If there are no adjustment parameters in the data­base, mathematically estimated parameters are applied based on known properties of the crucible and gas type. No extra adjustment is neces­sary, saving valuable time for the operator.

Innovative Robot with Gas-Purged Crucible Chamber
Protects Samples from the Environment and Operates Reliably Around the Clock

When using the sample robot, a large number of samples can be stored in the crucible chamber. To prevent unwanted interac­tions with the atmosphere before the samples are measured, the chamber can be purged with an inert gas, such as nitrogen.

The environmentally-controlled crucible chamber stores up to 96 sample crucibles and 7 ref­erence crucibles for continuous measurement. The DSC 5+ can automatically detect two different tray types that handle crucible sizes ranging from 20 to 160 μL.

The diagram below shows the innovative layering system of this revolutionary new sensor.

Layers of the MMS 1 Sensor
Multi Mode Sensor

The MMS 1 sensor of the DSC 5+ represents a huge leap in DSC technology. The inclusion of heating elements in the sensor allows a power compensation measurement mode. For the first time, a single furnace DSC can measure with power compensation. This provides a single sensor with an extremely fast signal time constant for high resolution, and a high signal-to-noise ratio for amazing sensitivity.

Layers 1 and 2
136 Thermocouples

The star-shaped arrangement of thermocouples measures the temperature difference between the sample and reference positions. With two layers of 68 thermocouples, the measurement signal is amplified, resulting in very low noise for a more sensitive DSC.

Layer 3
Heaters

Two Heaters for Power Compensation
Two integrated heaters (250 µW each) are located at the sample and reference positions and become active during measurements in power compensation mode. The aim of the power compensation mode is to keep the temperature difference between sample and reference close to zero.

Exothermic effect: The temperature on the sample side increases. The heater on the reference side will then activate, increasing the reference temperature until it equals the sample temperature.

Endothermic effect: The sample becomes cooler than the reference. The sample heater will then activate, increasing the sample temperature until it equals the reference temperature.

Layer 4
Temperature Sensors

Absolute Temperature Sensors
Two temperature sensors precisely measure the absolute temperature of the sample and reference.
