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 6200 Isoperibol
Calorimeter, are measured by a substitution proce-
dure in which the heat obtained from the sample is
compared with the heat obtained from a standard-
izing material. In this test, a representative sample
is burned in a high-pressure oxygen atmosphere
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.
