One-touch horizontal dual balance beam
The horizontal dual beam balance design ensures the gas flow is perpendicular to the weight direction. This means that there is no overall effect caused by purge gas flows and buoyancy effects, even when using gas flows as high as 1000 ml/min. Other effects such as chimney, convection and thermal molecular flow effects are also eliminated.
The patented one-touch type dual balance beam design allows the user to exchange the beam by themselves. The light weight balance beam gives the EXSTAR 6000 series TG/DTA the highest sensitivity and stability.
Other benefits include:
- high quality results for very low mass losses over the full temperature range
- drift-free baselines to ensure high sensitivity and high accuracy measurements
- SIINT patented advantage digital control technology to realise fast properties and ensure that there is no temperature overshoot.
Temperatures for both samples are measured at the sample, which means true sample temperatures are recorded (unlike many systems which only record furnace temperatures).
The EXSTAR series TG/DTA provides direct temperature calibration and pre-calibration functions by using high purity metal standards which are measured in the DTA mode. The thermocouple is in direct contact with the sample holder which ensures the very high precision temperature measurmement. In addition, the unique software design makes the precalibration very easy to perform.
Controlled rate Thermal Analysis (CRTA)
Controlled rate Thermal Analysis (CRTA) is supplied as standard . This unique measurement method automatically controls the heating rate in response to the physical property change of a sample.
Highway Measurement: simulate slow heat rates
The Highway method is a unique feature available as standard, designed to obtain data on very slow heating rates, based on measurements done at much higher rates. The method is based on advanced mathematical methods and provides accurate results.
Reactive Atmosphere handling
A separate purge port for reactive and corrosive purge gases is available. The separate port is designed to permit the introduction of corrosive or any special purge gases into the reaction chamber directly without going through the balance housing.
Reliable, Compact Auto Sampler
The EXSTAR 6000 series TG/DTA can be coupled with the rugged autosampler AST-2 for fully automated and unattended operation. With up to 30 sample positions and a mechanical finger design, the AST-2 offers reliable and fully-automated operation.
