熱重量測定 (TGA/TG) 

NETZSCH (ネッチ) 熱重量測定装置は、コンパクトで高感度天秤を備えています。トップローディング方式ですので操作が簡単で、試料温度は直接正確に測定可能です。

What is Thermogravimetry?

Thermogravimetric analysis is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as Phase TransitionsThe term phase transition (or phase change) is most commonly used to describe transitions between the solid, liquid and gaseous states.phase transitions, absorption and desorption; as well as chemical phenomena including thermal Decomposition reactionA decomposition reaction is a thermally induced reaction of a chemical compound forming solid and/or gaseous products. decomposition, and Solid-Gas ReactionsSolid-gas reactions are a type of heterogeneous solid-state reaction occurring when a reactive solid is exposed to a stream of reactive gas. Typical examples of solid-gas reactions are sorption and corrosion of metals.solid-gas reactions (e.g., OxidationOxidation can describe different processes in the context of thermal analysis.oxidation or reduction).


ほとんどの NETZSCH熱天秤は、真空タイト構造ですので特定雰囲気中での重量変化測定が可能です。

オプションの c-DTA® 信号を使えば、重量変化に関係のない試料の発熱、吸熱反応の情報も得ることができます。  

多くの熱天秤には、QMSFT-IR or GC-MS等のガス分析システムとの加熱接続アダプターを装備することができます。 

400シリーズ熱重量測定装置には、DSC やDTA サンプルキャリアーを装備することができますので、本来の
TGA-DSCまたは TGA-DTA同時測定装置 (STA)としていつでもお使いいただけます。
NETZSCH (ネッチ) 熱天秤はISO 11358, ISO/DIS 9924, ASTM E1131, ASTM D3850, DIN 51006を含む、様々な標準規格に準拠しています。
