Note: The unit of heat used in this manual is
the International Table calorie, which is equal
to 4.1868 absolute joules.
Purpose
Heats of combustion, as determined in an oxygen
bomb calorimeter such as the 6400 Automatic
Isoperibol Calorimeter, are measured by a substitu-
tion procedure in which the heat obtained from the
sample is compared with the heat obtained from a
standardizing material. In this test, a representative
sample is burned in a high-pressure oxygen atmo-
sphere within a metal pressure vessel or “bomb”.
The energy released by the combustion is absorbed
within the calorimeter and the resulting temperature
change is recorded.

Note About Nomenclature:
Historically, burning a sample enclosed in a high pressure oxygen
environment is known as Oxygen Bomb Calorimetry and the vessel
containing the sample is known as an Oxygen Bomb. The terms
bomb and vessel are used interchangeably.
