IKA calorimeters are technically engineered for the precise determination of the gross calorific value of solid and liquid samples. These instruments utilize the oxygen bomb combustion method, where a sample is completely oxidized in a high-pressure oxygen environment within a specialized decomposition vessel. The heat released during combustion is transferred to a water jacket.

IKA decomposition systems are technically engineered for the oxidative digestion of liquid and solid organic samples within a high-pressure, closed environment. This technical process is fundamental for the quantitative determination of halogens, as well as sulfur. During operation, an absorption solution is placed inside the digestion vessel to collect these elements as they are released during combustion.
