Detemination of OH Surface Density of TiO2 by Thermal Gravimetric Analysis (TGA) (CAT#: STEM-ACT-0040-WXH)

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction).

• Thermal characterization of polymers.
• Determination of the composition of alloys and mixtures.
• Determining the purity and thermal stability of both primary and secondary standards.

TGA analysis is performed by gradually raising the temperature of a sample in a furnace as weight is measured on an analytical balance that remains outside the furnace. Thermogravimetric analysis instrument measures the changes in a sample's weight in a particular temperature by enclosing the sample in an oven.
