-Researches of inorganic and organic materials: clay, metals, minerals, polymers, resin, oil, etc;
-Determination of thermal effects of adsorption and polymerisation;
-Qualitative determination of enthalpy of chemical and physical transitions;

Equipment:  
System of thermoanalysis METTLER TOLEDO (Switzerland)

Thermogravimetric Analysis

   Thermogravimetry (TG) - a method of the thermal analysis at which change of weight of a sample is registered depending on temperature. This method is effective in that case when the sample evolves flying substances as a result of various physical and chemical processes.

Differential Scanning Calorimetry

   Differential Scanning Calorimetry (DSC) differs from Differential Thermal Analysis (DTA) (about DTA, see below) and allows to register a thermal stream which characterizes changes occurring in substance as a result of heating or cooling. In this method the sample and the standard are heated up or cooled with identical speed, and their temperatures are supported identical.
