The STA 449 F1 Jupiter® runs under Proteus® Software on Windows® XP and Vista®. The Proteus® Software includes everything you need to carry out a measurement and evaluate the resulting data. Through the combination of easy-to-understand menus and automated routines, a tool has been created that is extremely user-friendly and, at the same time, allows sophisticated analysis. The Proteus® software is licensed with the instrument and can of course be installed on other computer systems.
TGA features:
- Mass changes in wt% or mg
- Automatic evaluation of mass-change steps
- Calculation of residual mass
- Extrapolated onset and end temperatures
- Peak temperatures of the 1st and 2nd derivative of the mass-change curve
- Automatic baseline and buoyancy correction
- c-DTA® for calculated DTA signal with evaluation of characteristic temperatures and the peak area (optional)
You can use the following software with this product:
DSC features:
- Determination of onset, peak, inflection and end temperatures
- Automatic peak search
- Transformation enthalpies:
Analysis of peak areas (enthalpies) with selectable baseline and partial peak area analysis
Enthalpy determination considering mass changes
Complex peak analysis with all characteristic temperatures, area, peak height and half-width - Comprehensive analysis of glass transitions
- Automatic baseline correction (TGA, DSC, DTA)
- Degree of crystallinity
- OIT (oxidative induction time) evaluation
- BeFlat® for automatic baseline correction
- Tau-R® Mode: takes into account the time constant and thermal resistance of the instrument and reveals thus sharper DSC effects from the sample (only in connection with DSC sample carrier)
- DSC correction: Evaluation of exo- and endothermal effects under consideration of system time constants and thermal resistance values
- Specific heat determination (optional)
- TM-DSC module software extension for temperature-modulated DSC tests (optional)
A variety of sample crucibles (pans) made of alumina, platinum, aluminum, graphite, fused silica, etc. is available in different sizes.
The water vapor furnace with perfectly balanced accessories for steam generation, gas mixing and flow control offers the unique opportunity to study the mass and energy changes in samples up to 1250°C under defined absolute humidity.
The high-speed furnace does not require a stand-alone instrument but extends the well-established instrument series STA-Jupiter® by another furnace type. The concept allows for equipping a measuring instrument with a double-furnace hoisting device for two furnaces. The high-speed furnace can therefore be mounted on the double hoisting device combined with other furnaces. Instead of a second furnace, an automatic sample changer (ASC) can optionally be used for the high-speed furnace. Modular flexibility and particularly the combinability of the high-speed furnace with the ASC saves a great amount of time and thus directly results in an increased sample throughput.
The automatic sample changer is designed for routine measurements. It works day and night, giving you time for other tasks, and provides for optimal use of the STA 449 F1 Jupiter® (e.g. calibrations on the weekend).
A carousel is available for up to 20 sample and reference crucibles (pans) which can be automatically run in any order. The controlled generation of the required gas atmosphere in the sample chamber and cooling are automatic.
Of course, each sample can be assigned an individual measurement and evaluation macro. Easy-to-understand input masks lead you through the programming of the measurement series. And it is always possible to insert unplanned analyses into a preprogrammed series of measurements that is already in progress.
PulseTA®
With the PulseTA® technique an exactly defined quantity of gas is injected to the purge gas of the thermobalance (TGA) or the simultaneous thermal analysis instrument (STA).
This clearly increases the measuring possibilities:
- Defined/incremental chemical reactions or adsorption of the injection gas with the sample
- Quantification of gases evolved from the sample.
