Thermogravimetric Analyzer

Thermal analysis is a study of the relation between the properties of a sample as a function of temperature. Thermogravimetric Analysis is a subdivision of the same, where the mass of a sample is measured as a function of temperature. That is, the sample is subjected to changes in temperature and its mass (or even the rate of change of its mass) is measured at different intervals of time.

The basic structure of a thermogravimetric analysis instrument consists of a pan and a furnace with a temperature control mechanism. There are two types of loading that the pan can have and these are top loading and bottom loading. Top loading pans have the pan placed on top of the balance with a support rod under it. In bottom loading pans, the pan hangs from the balance or the mass may be hooked onto it.

Different environments can be provided for the same sample, to study the effects of vacuum. These effects may be in the form of increasing or decreasing temperature, constant temperature, effects of different gaseous environments like moisture or corrosive gases, high and low pressures etc. The change in mass are then plotted on a graph, corresponding to the temperature, to obtain what is known as the TGA (thermogravimetric analysis) curve.

It is crucial to find out about the effects of temperature on different materials like plastics, polymers, composites, fibers, paints etc. to know how each would behave in a given environment. Thermogravimetric analysis can determine the thermal stability of the material and makes us aware of the maximum temperature upto which the material can be used without degrading. It also helps in material characterization which is to find out the physical and chemical properties of various materials. This benefits pharmaceutical companies, food industries, environmental studies and every industry that uses these materials.

For accuracy in studies in the field of thermal analysis, it is necessary to provide for a stable environment free of vibrations and other interferences while the experiments are carried on. A small degree of vibration from a neighboring instrument or air flow from an open door can significantly affect the performance and cause various problems like a baseline shift in the TGA curve, hence causing the final graphs to be inaccurate. We can supply you with a suitable platform to place your instrument to prevent it from experiencing these disturbances during its operation.
