         The Diamond Thermogravimetric/Differential Thermal Analyzer (TG/DTA) combines the high flexibility of the differential temperature analysis (DTA) feature with proven capabilities of the Thermogravimetry (TG) measurement technology. The combination not only ensures that the sample is exposed to identical thermal treatment and environment but allows one to deternmine whether an endothermic or exothermic transition is associated with weight loss in contrast to a melting or crystallization process.


  Instrument Details  
Thermal behaviour being one of the physical property of any material, it gives fair estimation of constituents, nature and usage of material. The traditionally adopted procedures for thermogravimetry and calorimetry are tedious, time consuming and involve elaborate human intervention. Modern thermal analysing systems overcome all the problems associated with the traditional techniques as they use versatile computers for setting up of experiment, its control, data acquisition/storage and analysis. Further, use of electronic sensors for physical measurements increase the sensitivity, accuracy and ease of operation.

  User Instructions   

        1. The charges for carrying out Thermal Analysis study is based on the total time spent in heating & cooling the sample which will depends on prescribed heating program.
         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 : Al,Ceramic and Pt(DTA, TGA). The user may please ensure that samples likely to react with the above materials will not be accepted for Thermal Analysis.
         5. For any halide compounds the upper temperature limit specified should be below the decomposition temperature.
         6. On account of overwhelming demand, the upper limit for the number of samples acceptable at a time is four (4).
         7. Minimum quantity of sample required is about 40 mg, each, for DTA / TGA, respectively.
         8. In order to safeguard the DSC cell from damage it is absolutely essential that you must state the decomposition products associated with heating cycle of your sample. Therefore, please furnish the following information. Sample No. Decomposition product Halogen Product
