Thermal Analysis Premium TMA/SDTA 2+ STARe System Innovative Technology Versatile Modularity Swiss Quality Thermomechanical Analysis for All Requirements

Outstanding Measurement Performance Thanks to Swiss Precision Mechanics Thermomechanical analysis (TMA) is used to measure dimensional changes of a material as a function of temperature. Thermal expansion and effects such as softening, crystallization and solid-solid transitions determine the potential applications of a material and provide important information about its composition. Viscoelastic behavior can be studied by varying the applied force (DLTMA mode). Features and benefits of the METTLER TOLEDO TMA/SDTA 2+: n Wide temperature range – from –150 to 1600 °C n SDTA – for the...

SDTA Signal Unsurpassed Temperature Accuracy The TMA/SDTA 2+ is the only instrument on the market that measures the sample temperature very close to the sample in all operating modes. This enables temperature adjustment to be carried out using reference substances (e.g. the melting points of pure metals) or through a change in length. The SDTA signal is the difference between the measured sample temperature and the reference temperature calculated using a model (US Patent 6146013). This means that besides the length change, the simultaneously measured SDTA signal is also available as a...

Rapid Results Thanks to Innovative Solutions Easy sample installation The sampling area is freely accessible for installing the sample holder and measuring probe. These operations can be performed quickly and easily. An indentation ensures that the sample holder can only be installed in one position. The measuring probe is securely attached to the length sensor (LVDT) by means of a magnet and can easily be changed. Different sample holders and measuring probes are available for each measuring mode. This allows you to choose the best configuration for each application. Complete thermal...

This ensures that calibrations are performed reliably and easily. • The touch screen can be used to control the determination...

Swiss Qualitiy Reliable, First-Class Performance Over the Entire Temperature Range Measurement principle Thermomechanical analysis measures the change in length of a sample as a function of temperature and the applied force. 11 Wide measurement range 16 000 000 data points are available for the entire measurement range of ±5 mm. This means that both small and large samples (maximum 20 mm) can be measured with 0.5 nm resolution without the need for range switching. Thermostating The mechanical part of the measuring cell is accommodated in a thermostated housing. This guarantees excellent...

Optimized Sample Holders for Quick and Easy Handling The TMA/SDTA 2+ offers various accessories that enable you to measure samples in different deformation modes. The most suitable mode for your particular application depends on the nature and properties of the particular sample. The various deformation modes Dilatometric mode (A): This is the mode most commonly used in thermomechanical analysis. The expansion coefficient is determined as a function of temperature. A typical feature of this mode is that the probe exerts only a very small force on the sample. Compression mode (A): In this...

Unparalleled versatility Optimum Measurement Configurations The four TMA/SDTA 2+ versions The TMA/SDTA 2+ is available in four versions: • A high-temperature version for measurements from room temperature to 1600 °C. • A standard temperature version for measurements from room temperature to 1100 °C. • An IntraCooler version that operates from –80 to 600 °C. The IntraCooler is the most effective cooling option on the market that operates without the use of liquid nitrogen. • A liquid nitrogen cooling option for the low temperature range from –150 to 600 °C. Conversion from one TMA version to...

Wide Variety of Applications Thermomechanical Analysis for a Wide Range of Applications The TMA/SDTA 2+ can be used for a wide range of applications due to its broad temperature range and the wide choice of force parameters in compression and tension modes. As a result, the TMA/SDTA 2+ quickly provides characteristic information on numerous types of samples, for example very thin layers, large sample cylinders, fine fibers, films, plates, soft or hard polymers, and single crystals. Complementary technique TMA is the ideal addition to DSC. Besides the measurement of expansion coefficients,...

CTE determination The coefficient of thermal expansion (CTE) can be determined from TMA measurements in the DLTMA mode. The diagram shows dilatometric curves and the resulting expansion coefficients of three different materials. Borosilicate glass has a CTE of about 3.3 ppm in the glassy state and a glass transition at about 550 °C. Invar is a iron-nickel alloy, which shows practically no thermal expansion up to 150 °C. Crystalline α-quartz expands with a continuously increasing expansion coefficient. A solid-solid transition to β-quartz occurs at about 575 °C. On further heating, the...
