Thermogravimetry (TGA) measures weight changes in a material (subjected to temperature variation in a controlled atmosphere).
All SETARAM Instrumentation's balances satisfy the highest accuracy and stability criteria.
Properties measured by thermogravimetry (TGA) include corrosion, pyrolysis, adsorption / desorption, loss of solvent, oxidation / reduction, hydration / dehydration, decomposition, carbon black, etc,.
SETARAM Instrumentation offers several systems:
SETSYS Evolution, High Performance and modular Thermogravimetric Analyzer (ambient to 2400°C)
LABSYS, easy-to-use Thermogravimetric Analyzer (ambient to 1600°C)
96 LINE, large volume and high temperature Thermogravimetric Analyzer (ambient to 2100°C) |

TG 209 F3 Tarsus - Thermo-Microbalance
Together with the DSC 200 F3 Maia®, the new thermo-microbalance, TG 209 F3 Tarsus, represents a cost-effective overall concept, tailored not only to the quality assurance of polymers, but also to routine applications in the fields of organic chemistry, pharmaceuticals, cosmetics and food.
This new basic instrument for thermogravimetric measurements offers already a resolution of 0.1 µg. The TG 209 F3 Tarsus operates between room temperature and 1000°C with freely selectable heating rates from 0.001 K/min up to 100 K/min. The accurate sample temperature is detected by a thermocouple in direct contact with the sample crucible. Through the reliable vertical construction with sample carrier lift, the thermo-balance as a top-loader, is easy and safe to use, with no hang-down wires or exposed fragile parts.
The calculated DTA-signal c-DTA® (option) not only is ideal for temperature calibration. During sample measurements it yields important information regarding endothermal processes (e.g. vaporization with mass loss or melting without mass loss) as well as exothermal reactions.
For the TG 209 F3 Tarsus we offer an automatic sample changer (ASC) for up to 20 samples also in different crucible types.

| Thermogravimetric Analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. Thermogravimetric Analysis instruments are routinely used in all phases of research, quality control and production operations. TA Instruments offers the Q5000IR, Q500, Q50, and simultaneous DSC / TGA (Q600) to meet the various needs of the researcher, quality control analyst and academic instructor. |

TMA 402 - Vertical thermomechanical analyzer
The TMA 402 thermo-mechanical analyzer combines in a unique way the flexibility for investigation of samples under loads of various types and configurations with extremely precise, high-resolution determination of expansion and deformation. This is achieved through the vertical design, with the very homogeneous furnace at the bottom and thermostatically controlled measurement system at the top.
Easy handling and exchangeable sample holders for expansion, penetration, bending and tension measurements, as well as load selection via standard weights, mean quick sample preparation and measurement.
Dynamic elasticity measurements are possible with an electromagnetic dynamic load accessory.
Polymers, composite materials, glass, ceramics and metals are among the preferred application materials in the form of cylinders, rods, small plates, films, fibers or wires. |

Voltammetry instruments and polarographs are favorably priced and compact, yet great in their detection capabilities.
- With voltammetry you can analyze trace elements in water, environmental samples or ultrapure chemicals!
- With the Cyclic Voltammetric Stripping technique (CVS) the analysis of organic additives in plating baths can be carried out easily and accurately.
Convincing applications
1) Apart from the determination of the total concentration, voltammetry allows to distinguish the different oxidation stages of metal ions or differentiate between free and bound metal ions as well as to specify the biological availability of heavy metals. VA instrument can also be used in mobile laboratories for environmental analysis.
2) Not only metals but also various organic compounds can be determined by voltammetry, but also some special anions. The determination of environmentally relevant anions like cyanide, sulfide, nitrite or nitrate is particularly interesting.
Automation makes work easier, increases sample throughputs and provides more exact results. For example, the CVS determination of organic additives in the plating industry can be carried out manually, partly automated or fully automated using the 838 Advanced Sample Processor. |
