3.1 Determinations and Titrations
Unlike other Metrohm instruments, the 726 Titroprocessor offers the ability
to include up to five titration or measuring modes in one method.
One method defines a determination to be done with one sample. This de-
termination may include multiple titrations or measurements. Each one of
these modes may include separate calculation formulas and report defini-
tions. Each mode produces its own data sets (measuring point list), which is
the origin for any report to be printed or sent to an external device such as a
PC or a LIMS.
Methods and determinations can be stored in separate files, either on a
data card or in the internal storage of the 726.

Determinations can be reloaded and modified. Recognition and display set-
tings can be changed. All formulas can be modified and recalculated. Even
a re-evaluation of the endpoints is possible. A new set of reports may be
defined and printed.
Common variables that have been valid at determination time are stored
with the determination data and may be used for recalculations as tempo-
rary common variables. Recalculations do not have an effect on the global
common variables.
Multiple (but similar) titration and measuring curves may be compared by
overlaying.
