TOKYO -? Hitachi High-Tech Science Corporation (Hitachi High-Tech Science,

President: Toshiyuki Ikeda) announced the worldwide release of the STA7200RV, a pioneering

thermogravimetry/differential thermal analyzer that can observe and measure samples at

temperatures up to 1,000°C by using a sample observation option.

Thermal analyzers are instruments that measures fundamental material properties (thermal

properties) of heat. For example, differential thermal analyzers (DTA) and differential scanning

calorimeters (DSC) measure the heat flow to a material. Thermogravimetry (TG) measures the

weight change. Thermo mechanical analyzers (TMA) measure the deformation of a material, while

dynamic mechanical analyzers (DMA) measure elastic modulus. Thermal analyzers are used in

various fields including the research and development of materials and in quality control. Hitachi

High-Tech Science is a top maker of thermal analyzers in Japan.*

Since the results of thermal analysis are generally expressed as a graph, users obtain the thermal

properties of the sample from tiny changes in the graph. By combining a CCD camera and special

software with a thermal analyzer, Hitachi High-Tech Science began marketing models with a

sample observation option** that allows users to observe visible changes of the sample during

measurement. Together with continuous images taken by a CCD camera that shows the state

change of the sample, users can now evaluate the measurement results while observing the

sample, something that could not be done via usual thermal analysis methods, leading to higher

reliability.

The STA7200RV Differential Thermal Analyzer is able to measure and observe samples at

temperatures up to 1,000°C in contrast to conventional models that make measurements up to

500°C. The high temperature is achieved by a newly designed heating furnace with a sample

observation window (view port). The STA7200RV lets you observe the entire decomposition process

of a high molecular organic material, which conventional models are not capable.

Main Features Main Features

1) The new heating furnace with view port allows for sample observation at temperatures up to

1,000°C.

2) Simple operation. Users set the sample observation option, adjust the focus, and start

measurement and observation.

3) Simultaneous observation and measurement can be performed by combining the STA7200RV

with a thermogravimetric analysis-mass spectrometer (TG-MS) or thermogravimetric

analysis-infrared spectrophotometer (TG-IR). With the addition of sample observation data,

reliability of analysis is further increased.

4) The measurement and analysis software for sample observation can be shared with DSC, DMA,

and other tools. The software displays and saves continuous images that show the state change

of the sample during measurement. The images can be retrieved and linked with temperature

and other signals for analysis.
