Because the core of a thermogravimetric analyzer is its balance, SETARAM Instrumentation designs balances exclusively for thermal analysis applications. Three models of balance are offered with THEMYS, namely HIGH SENSITIVITY, HIGH CAPACITY and HIGH VERSATILITY.
They are all based on the hang-down design, providing the highest level of stability and the best limit of detection.
The THEMYS offers the user to choose the right crucible for the right experiment:
- Choose standard cylindrical crucibles or more dedicated ones, like meshed or three-tray crucibles for better gas sample interactions,
- Choose the volume related to your sample size, ranging from 130 μl to 2.5 ml,
- Choose the most inert crucible material for your sample, atmosphere and temperature range: finest quality platinum, tungsten, quartz, alumina, or graphite.
Bulk materials can also be held directly on a suspension hook without any crucible, for the best gas sample interactions.
Furnace and temperature control
THEMYS is designed around a single, robust and high performance graphite furnace providing a large homogeneous temperature zone required by changing experiments: small or large samples, small TGA crucibles or large tricouple DTA rods, etc. This also avoids tedious furnace exchange when experiment conditions change.
This furnace principle is consistent with the traditional SETARAM effort for providing systems with the lowest operational costs in the market.
A choice of high sensitivity thermocouples to cover changing temperature range needs is provided with an easier than ever TWIST AND LOCK system.
3 options, PureGas, GasBlend and MultiGasBlend, are made available with increasing capacities to generate and control complex atmospheres. They all have in common an intelligent software control system for sequentially changing the gas types, flowrates, or blend ratios during the experiment or sample pretreatment.
Primary, Forced Primary or Secondary Vacuum options are available with a selection of adapted vacuum pumps.
Specific accessories are designed for samples under really harsh conditions while protecting the thermal analyzer. Sleeved thermocouples (alumina) and protected DTA rods are available.
