Product description TG 209 F1 Libra
The vacuum-tight thermo-microbalance with great precision!
Based on more than 50 years of experience in thermogravimetry, Netzsch has developed the thermo-microbalance TG 209 F1 Libra. This instrument allows for analysis to be carried out even faster, more accurately, and across an extended temperature range.
Unlike other thermal microbalances, the TG 209 F1 Libra does not normally require time-consuming basic measurements prior to a measurement. The unique BeFlat® function of the Libra automatically compensates for all external factors that influence the measurement. This functionality reduces the time required for a measurement by approximately 50%, leaving more time available, for example for further measurements.

The heart of the TG 209 F1 Libra® is the micro furnace made of high-performance ceramics. It not only allows for a wider sample temperature range of up to 1100°C, but also for heating rates of up to 200 K/min. The user can therefor receive the results of the analysis – even at highest temperature – within a few minutes, i.e. 20 times faster than for other thermo-microbalances.
Several sample holders are available, including corrosion resistant sensors, high sensitivity c-DTA® sensors for enhanced monitoring of endo- and exothermic effects, and special sensors for large sample masses. The sample holder can be easily exchanged in less than one minute.
Endo- and exothermic reactions can be detected automatically and thus show, for example, the melting point of the sample in the evaluation. This provides significantly more information about sample behavior without having to perform additional measurements.
Netzsch TGA features:
- Mass changes in % or mg
- Automatic evaluation of mass change steps
- Determination of mass and temperature variations
- Determination of the residual mass
- Extrapolated onset and endset
- Peak temperatures of the 1st and 2nd derivative of the mass change curve
- Automatic base and drift correction
- c-DTA® for the calculated DTA signal for recognition of endo- and exothermic reactions
- Super-Res® for automatic rate controlled mass change and high resolution temperature programs (optional)
The lifespan of the new, specially designed ceramic furnace, is much longer than that of conventional thermobalances. This has been shown even when examining materials containing corrosive components. Therefor the analysis of fluorinated or chlorinated polymers is no problem. The reaction and purge gases flow in the natural vertical direction, efficiently and completely removing any sample degassing. Condensation on crucial components, such as the sample holder, for example, can therefore be excluded. This is not only better for the sample and the measurement itself, but also prevents the occurrence of the dreaded memory effect, which can interfere with subsequent measurements in conventional systems.
Proteus Software
The Proteus® Software offers everything you need to perform the analysis and evaluate the data. By combining easy-to-understand menus and automated routines, a tool has been created that is extremely user-friendly while also enabling advanced analysis
AutoEvaluation and Identify are new features added to Proteus version 8 for automatic curve evaluation at the click of a button and identifying unknown polymer curves. With this, even inexperienced users are able to obtain fast, safe and meaningful results.
Results generated through AutoEvaluation can be manually verified and calculated, giving the user full control over the evaluation process. Each Proteus version is linked to the specific instrument, but can of course be installed on other/multiple computer systems.
