Facility Features, Working Principle and Specifications
Facility Description
The Thermo Gravimetric Mass Analyzer (TG-MS) features a skimmer-type interface combined with fragment-free photoionization technology, enabling the measurement of molecules without destruction. The system's high-precision gas introduction interface and soft photoionization technology allow real-time discrimination and analysis of generated gases, even when multiple components are present simultaneously. This advanced configuration is ideal for analyzing complex gas mixtures during thermogravimetric experiments.
TG-MS, a simultaneous technology coupling thermogravimetry (TG)—which determines mass change as a function of temperature—and mass spectrometry (MS), is a typical method in evolved gas analysis (EGA).
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.
