The Heat capacity is a measurement which describes the amount of energy (heat) needed to raise the vessel temperature by 1 degree. It is measured in Kj/c.

In simple terms: The heat capacity (or Bomb Factor, BF) is calculated during the calibration and then it is applied to the unknown samples.

This is not the complete picture: Many more variables are attached to the BF during a calibration, and all this is saved per vessel and operating mode. For details see: CALIBRATION MANAGEMENT

The following is an approximation of the heat capacity:

The Heat capacity of the vessel is approx. 0.001C/J or 1KJ/C. In practical terms it means that 0.5g Benzoic Acid results in 0.5g*26.454Kj/g = 13.227Kj

This results in approx. 12.6C temperature Rise.

Therefore: The heat capacity is 13.227Kj / 12.6C = approx. 1.05 Kj/C

The above calculation is performed by the calorimeter to 6 decimal places. It is then recorded to the vessel number (and mode, if applicable). The user is not concerned with the BF.

The heat capacity (BF) changes with the weight and the vessel constitution.

This feature applies to the following CAL3K Systems : CAL3K-AP , CAL3K-A , CAL3K-F
