The generic designation for a family of analytical methods in which the enthalpy
change of a chemical reaction is measured, directly or indirectly, in order to perform
a quantitative determination of a reactant or catalyst
. In general, at least one reactant is a liquid or solution. It is a subset of calorimetry
in which the system is maintained at constant (usually atmospheric pressure), and
the emphasis is on a quantitative determination in a reasonable length of time. Analytical
solution calorimetry is a synonymous designation that may be used but is not preferred.
has been used but is not recommended because of potential confusion and overlap with
the methods of thermal analysis
. The adjective thermometric
is also associated with the names of some of these methods, but is not recommended
as a general designation.
