What is Calorimeter?

Calorimetric measurements involve the use of various units of temperature and energy. The relationships between them should be well understood so that there is no error and confusion during the interpretation of the resulting data. Calorimetry is the science of measuring the amount of heat released or absorbed from matter. The instruments used for calorimetric measurements are known as calorimeters. The calorimeter is used to measure the calorific values of solid and liquid combustible samples. The usage areas of calorimeter instrument for calorific value analysis include coal analysis, explosive analysis, fuel analysis, food/feed analysis, oil analysis, waste product analysis.

The calorific value of a sample can generally be defined as the amount of heat released by the unit mass of the sample when burned with oxygen in a constant volume container. While measuring the calorific value of a sample, a bomb calorimeter device that provides controlled conditions (constant volume) is used. A solid or liquid combustible sample of a certain weight is placed in the crucible and placed in the decomposition vessel (bomb). The decomposition vessel is filled with high pressure (30 bar). The sample is ignited by the electrodes and the reaction is started. After the reaction starts, heat is released. The heat generated in the vessel increases the temperature of the water in the analysis chamber. The calorific value of the sample is calculated with the temperature increase in the water in the calorimeter analysis chamber.

What Is Measured with Calorimeter?

With calorimeter, calorific value analysis of both solid and liquid combustible materials can be performed. It enables the measurement of critical measurements such as coal calorific analysis with high precision. The calorimeter instrument can also be used for calorific analysis of fuels such as petroleum. It is also used in the food industry to measure the calorific value of foodstuffs and products such as animal feeds. It has other usage areas such as explosive analysis, oil analysis, waste product analysis.

For example, bomb calorimeter can be used as a coal analyzer for the calorific analysis of coal. The calorific value is a measure of heating ability of the coal and is necessary to determine the amount of coal needed to produce the desired amount of heat. Calorific value is a measure of the amount of energy produced from a unit weight of coal when burned in oxygen. To determine the calorific value of the coal sample, the sample is burned in the calorimeter and the resulting heat is calculated by means of the temperature difference in the water.

The calorific value is equivalent to the amount of heat energy required to raise the temperature of 1 gram of water by 1°C.

(1 cal = 4.184 J). The calorific value of a sample is calculated by calorimeter in j/g or cal/g.

What is Bomb Calorimeter?

The isoperibol calorimeter, or bomb calorimeter, is a type of calorimeter used to determine the calorific value of samples in a constant volume. The bomb which gives the name to the calorimeter is the decomposition vessel. The decomposition vessel is surrounded by an analysis chamber filled with water. The water found in the analysis chamber is kept at a constant temperature without being affected by the external environment. The sample in the decomposition vessel is ignited with high pressure oxygen (30 bar) via electrodes. With the burning of the combustible sample, the vessel heats up and the water in the analysis chamber begins to heat up. By measuring the change in water temperature, the calorific value of the sample is calculated.

For precise measurements, the temperature of the bomb calorimeter analysis chamber should be kept constant through the jacket. Our isoperibol calorimeters have specially designed analysis chamber to keep the water temperature constant. Ambient temperatures have a very low effect on the system thanks to the analysis chamber with a low heat capacity, which is unique to us. At the same time, the integration of the circulator system with cooling and heating features into the calorimeter ensures that the water is kept at a constant temperature and the calorific analysis results are stable. Our isoperibol calorimeters have features such as automatic water filling/emptying, automatic ignition, 0.0001°C measurement accuracy, less than 16 minutes analysis time, less than 0.1% RSD, integrated oxygen filling apparatus, integrated water circulator system.

With our PC control software, you can view graphics during and at the end of the analysis, access your past analysis and save them to your computer as pdf/excel if you wish. In addition to these features, thanks to the software, in case of an error in the system, you can receive instant notification and detect errors without wasting time. You can perform manual control of the hardware elements of your calorimeter instrument. With our calorimeter PC control software, you can perform easy and user-friendly control of your calorimeter instrument. In addition to the computer software, you can also control the calorimeter from the touch screen on the calorimeter.
