Seeing is Believing

Rigaku’s Sample Observation technology provides immediate visual confirmation of what is happening with a sample through a heating or cooling cycle with synchronized recorded video observation of the sample. This is particularly helpful for confirming melting and/or crystallization events in testing novel materials. Changes in shape and color can easily be observed. This is invaluable when trying to differentiate endothermic heat events, such as a melt vs a decomposition, or exothermic heat events, such as a crystal-crystal phase change vs a decomposition. This innovative capability helps researchers to understand more about specific events that could be mistakenly interpreted as noise without visual confirmation.

Differential Scanning Calorimeter (DSC)

Differential scanning calorimetry (DSC) quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature and is mainly used for research and development; and quality control in the fields of polymer, pharmaceutical.

The high-sensitivity type DSCvesta has several available options, such as a refrigerated cooling system, an automatic sample changer, sample observation, depending on the objective of the measurement.

Simultaneous Thermal Analysis (STA)

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA), an analytical technique that simultaneously measures thermogravimetry (TG) and differential thermal analysis (DTA). Rigaku’s TG-DTA adopts the horizontal differential triple-coil balance that cancels various fluctuations causing TG drift to achieve highly accurate weight change measurements.

Also, the sample-controlled TG (SCTG) method is equipped as a standard. Sample observation TG-DTA can perform measurements while capturing visual images of the sample with a CCD camera. Through these images, we can observe shape changes or color changes in the sample associated with a reaction. These images are helpful in interpreting TG-DTA results.

Thermomechanical Analysis (TMA)

TMA is a technique in which a non-oscillatory load is applied such as in compression, tension or bending, measuring the changes in the sample shape when the sample is heated or cooled. The TMA method includes measurement modes such as compression loading method, tensile loading method, penetration method based on the sample shape and the objective of the measurement. TMA is widely used to measure the thermal expansion ratio and softening temperature of a sample.

Rigaku’s TMA adopts the differential expansion principle that cancels the thermal expansion or shrinkage generated from the detection mechanism itself. In addition to constant load, the load control can be set to two types: constant rate loading mode and sine-wave cyclic loading mode. Sample controlled TMA (SCTMA), where the shrinkage rate controls the temperature, can be installed as an option that is effective for the simulation of sintering in ceramics, production of sintered materials with suppressed grain growth.

High Temperature DSC

Differential scanning calorimetry (DSC) quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature, and is mainly used for research and development; and quality control in the fields of polymer, pharmaceutical.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C. In cases where high-temperature measurement is necessary—such as in ceramics and glass materials; as well as in measurements where multiphase phenomena can be obtained which cannot be measured by a standard DSC—the high-temperature type DSC is more versatile and applied to a wide range of fields.
