Constant temperature calorimeterIt is an instrument specifically used to measure the thermodynamic properties of substances, with a wide measurement range and can be applied to measure the thermodynamic properties of various substances. Here are some substances and their thermodynamic properties that can be measured by a constant temperature calorimeter:

1、 Material type

Inorganic substances

Various metals and their compounds, such as iron, copper, aluminum and their oxides, salts, etc.

Inorganic non-metallic materials, such as ceramics, glass, etc.

Organic substances

Various organic compounds, such as hydrocarbons, alcohols, esters, acids, etc.

Biomacromolecules such as proteins, nucleic acids, etc. (although these substances typically require measurement in more complex calorimeters, but...)Constant temperature calorimeterIt can also be used for preliminary research on its thermodynamic properties under appropriate conditions.

polymer materials

Polymer compounds such as plastics, rubber, synthetic fibers, etc.

Fuel and Energy Substances

Coal, oil, natural gas and other fuels, as well as energy materials such as lithium-ion batteries and solar cells.

2、 Thermodynamic properties

heat capacity

A constant temperature calorimeter can measure the specific heat capacity of a substance at different temperatures, which is a measure of the temperature change when a substance absorbs or releases heat.

Thermal desorption

Certain substances release gases or volatile substances during the heating process, and a constant temperature calorimeter can measure the changes in heat during this process.

heat fusion

For solid substances, a constant temperature calorimeter can measure the change in heat during their melting process, known as hot melting.

Thermochemical reaction

A constant temperature calorimeter can measure the changes in heat during chemical reactions, including endothermic and exothermic reactions. By measuring the difference in heat before and after the reaction, the thermal effect of the reaction can be calculated.

Other thermodynamic parameters

Based on measurement data and thermodynamic principles, thermodynamic parameters such as enthalpy and entropy of substances can also be derived, further understanding the thermodynamic properties of substances.
