Dilatometry

Dilatometry (DIL) is a technique in which a dimension of a substance under negligible load is measured as a function of temperature while the substance is subjected to a controlled temperature program in a specified atmosphere.

Linseis produces a wirde range of Single - Dilatometer, Differential - Dilatometer, Quattro - Dilatometer, Quenching Dilatometer and Optical Dilatometer.

Certainly Linseis Dilatometers comply with all national and international standards related to thermal expansion measurements, such as: ASTM E228, E289, E831, D696, D3386, DIN ISO 7991, DIN EN 821, DIN 51045.

Thermomechanical Analysis - TMA

Thermo mechanical analysis (TMA) easily and rapidly measures sample displacement (growth, shrinkage, movement, etc.) as a function of temperature, time and applied force.

Traditionally, TMA is used to characterize linear expansion, glass transitions, and softening points of materials by applying a constant force to a specimen while varying temperature. For expansion measurements, a probe rests on a sample on a stage with minimal downward pressure. Other constant force experiments include measurement of penetration, bending, tension, shrinkage, swelling, and creep (sample motion measured as a function of time under an applied load).

In Dynamic TMA (DTMA), a known sinusoidal stress and linear temperature ramp are applied to the sample, and the resulting sinusoidal strain is measured.

Differential Scanning Calorimetry - DSC

The Differential Scanning Calorimetry (DSC) is the most popular thermal analysis technique to measure endothermic and exothermic transitions as a function of temperature.

The instrument is used to characterize polymers, pharmaceuticals, foods/biologicals, organic chemicals and inorganics. Transitions measured include Tg, melting, crystallization, curing, cure kinetics, onset of oxidation and heat capacity.

Electrical Resistance

Thermal power generation is a method of generating power based on the thermoelectric effect which was discovered by J. T. Seebeck, German physicist in 1821. In the face of recent global warming caused by carbon dioxide and depletion of fossil fuels, thermoelectric conversion devices are attracting attention because of its effective utilization of waste heat energies. To meet these pressing requirements, a characteristic evaluating instrument for these materials and devices has been developed.

Thermal Conductivity

Information of the thermo physical properties of materials and heat transfer optimization of final products is becoming more and more vital for industrial applications. Over the past few decades, the flash method has developed into the most commonly used technique for the measurement of the thermal diffusivity and thermal conductivity of various kinds of solids, powders and liquids.

The Linseis LFA 1000 Laser Flash is the most modular and precise Instrument for the determination of Thermal Diffusivity, Conductivity and Specific Heat Values. Its sample robot for up to 6 Samples at the same time allows unbeaten turnaround times. The three user exchangeable furnaces allow measurements from -125 up to 1600°C.

A number of different sample holders for applications such as solids, liquids, melts and slags are available. The compact design allows the separation of hardware and electronics as well as the installation under a hood for nuclear applications.

Thermal Diffusivity - Thin Films

Information of the thermo physical properties of materials and heat transfer optimization of final products is becoming more and more vital for industrial applications.

Over the past few decades, the flash method has developed into the most commonly used technique for the measurement of the thermal diffusivity and thermal conductivity of various kinds of solids, powders and liquids.

Thermophysical properties from thin-films are becoming more and more important in industries such as, phase-change optical disk media, thermo-electric materials, light emitting diodes (LEDs), phase change memories, flat panel displays, and the semiconductor industry. All these industries deposit a film on a substrate in order to give a device a particular function. Since the physical properties of these films differ from bulk material, these data are required for accurate thermal management predictions.

Based on the well established Laser Flash technique, the Linseis Laserflash for thin films (TF-LFA) now offers a whole range of new possibilities to analyze thermophysical properties of thin films from 80nm up to 20 μm thickness.

High Speed Laserflash Method (Rear heating Front detection (RF)):

As thermal properties of thin layers and films differ considerably from the properties of the corresponding bulk material a technique overcoming the limitations of the classical Laserflash method is required: the “High Speed Laserflash Method”.

The measurement geometry is the same as for the standard Laserflash technique: detector and laser are on opposide sides of the samples. Because IR-detectors are to slow for measurement of thin layers, detection is done by the so called thermoreflectance method. The idea behind this technique is that once a material is heated up, the change in the reflectance of the surface can be utilized to derive the thermal properties. The reflectivity is measured with respect to time, and the data received can be matched to a model which contains coefficients that correspond to thermal properties.

Time Domain Thermoreflectance Method (Front heating Front detection (FF)):

The Time-Domain Thermoreflectance technique is a method by which the thermal properties (thermal conductivity, thermal diffusivity) of thin layers or films. The measurement geometry is called “front heating front detection (FF)” because detector and laser are on the same side of the sample. This method can be applied to thin layers on non-transparent substrates for which the RF technique is not suitable.

Thermal Conductivity

The Linseis Transient Hot Bridge - Thermal Conductivity Meter enables thermal conductivity, thermal diffusivity and specific heat measurements on various sample geometries and materials. This Linseis measuring instrument provides the three material properties simultaneously after just a few minutes time regardless of whether you have used the patented sensor in a solid matter (incl. bulk material, gels, pastes) or in a liquid. The preparation of solid samples is pretty simple: One pla-ne surface of two sample halves is sufficient for the sensor. Reference or calibration measurements are a thing of the past. As a matter of course, the THB measures absolute values, with an uncertainty which is not behind that of conventional plate or our laser flash devices.

Different sensors, easily to be exchanged, are available for laboratory and field use. The THB measures fully automatically. Its software control optimizes the measurement process independently, aiming at a short duration and a minimum uncertainty.

Advantages:

Highest AccuracyAbsolute technique (no calibration or reference sample required)
Fast measurement cyclesNon destructive measurement
Broad measuring rangeBroad temperature range
Easy handling (no trained staff required)
Simple sample preparation
Applicable for solids, liquids, powders and pastes
No influence of sensor contact pressure on measurement
Easy measurement of porous and transparent samples
