Thermogravimetric analysis of solid and liquid samples in different gas environments

 TG 209 F1 Libr 

One advantage of the TG 209 F1 Libra is its vertical, top-loading design which guarantees free and safe access to the crucible – there is no hang-down wire with any danger of bending, and no horizontal beam where crashing can occur. When placing the crucible on the sample carrier, there is no effect to the microbalance since the sample carrier is detached by an automatic lifting device. Sample placement is therefore always trouble-free.

The maximum temperature of the corrosion-resistant microfurnace amounts to 1100°C (sample temperature). Its high heating rates of up to 200 K/min are suited for identifying the material by a fast QC check. A water-cooled jacket provides the micro-furnace with fast cooling and therefore allows for high sample.

The precise ultra-microbalance under thermostatic control provides high resolution of 0.1 μg in the large mass measurement range of 2000 mg. Samples with a large mass change can be continuously analyzed at a high precision level without switching measurement ranges.

The automatic sample changer (ASC) is designed for routine quality control and assurance measurements. The single carousel accommodates up to 64 samples, even if these are in different crucible types with different geometries. Crucibles can be changed safely and reliably around the clock – even over the weekend. Each sample can be assigned a different measurement and evaluation program.
