Facility Features, Working Principle and Specifications
Facility Description
The Differential Scanning Calorimeter (DSC) is used to quantify the energy changes occurring during phase transitions, such as melting (Tm), solid-solid phase transitions, crystallization (Tc), and glass transition (Tg) temperatures. It is widely employed in research and development as well as quality control, particularly in the fields of polymer science, pharmaceuticals, and glass research.
Differential scanning calorimetry (DSC) works by measuring the difference in thermal energy applied to a sample and a reference material as a function of temperature. The device that performs this measurement is called a differential scanning calorimeter, or DSC
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 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 (~25 mg).
2) The analysis can't be carried out if the temperature range and the heating rate/ heating cycle are not specified.
3) Explosive, poisonous samples and samples giving rise to toxic/obnoxious gases/fumes on heating cannot be undertaken for DSC.
4) The sample holders are of Aluminum (Al) and Platinum (Pt). The user must ensure that samples will not react with crucible materials during DSC Analysis.
5)TGA data is mandatory for any DSC analysis. Without TGA data, DSC analysis will not be
performed. Weight loss during TGA should not be more than 2% for DSC analysis range.
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.
