Facility Features, Working Principle and Specifications
Facility Description
The Thermo Gravimetric Analyzer (TGA) measures a sample's change in weight as a function of temperature, enabling detailed analysis of reactions such as dehydration, thermal decomposition, evaporation, and oxidation. Additionally, Differential Thermal Analysis (DTA) detects endothermic and exothermic reactions during phase transitions, melting, crystallization, decomposition, and glass transition temperatures.
Rigaku’s TGA utilizes a horizontal differential triple-coil balance, designed to cancel out fluctuations and ensure highly accurate weight change measurements, providing robust data for thermal analysis.
In thermogravimetry, measuring the sample’s change in weight enables us to analyze the reaction temperature and the rate of weight change in reactions such as dehydration, thermal decomposition, evaporation, oxidation. Differential thermal analysis (DTA) measures the endothermic or exothermic reaction temperatures such in transition, melting, crystallization, dehydration, decomposition, oxidation and glass transition temperature.
Instructions for Registration, Sample Preparation, User Instructions and Precautionary Measures
An appointment will be given as per the queue and will be informed by email.
New users are requested to contact the facility before registration
At least 48 hrs prior information should be given to facility lab if users want to cancel/postpone the slot
1) Sample form: powder (~10 mg).
2) The analysis can not be carried out if the temperature range and the heating rate are not specified.
3) Explosive, poisonous samples and samples giving rise to toxic/obnoxious gases/fumes on heating cannot be undertaken for Thermal Analysis.
4) The sample holders are of Aluminum (Al) and Platinum (Pt). The user must ensure that samples will not react with crucible materials during Thermal Analysis.
In order to safeguard the instrument from the damage it is absolutely essential that you must state the decomposition products associated with the heating cycle of your sample. Any functional group which might potentially explode, or form foams is strictly not allowed (Representative examples are Azide, Perchlorate, poly-nitro or nitrogen-rich compounds, etc.) Explosive, poisonous samples and samples giving rise to toxic/obnoxious gases/fumes on heating cannot be undertaken for Thermal Analysis.
