commands

Commands for titrations.

Modes

The following titration commands can be selected:

DET

Dynamic Equivalence Point Titrations.

MET

Monotonic Equivalence Point Titrations.

SET

Set Endpoint Titrations.

KFT

Volumetric Karl Fischer Titrations.

KFC

Coulometric Karl Fischer Titrations with voltametric measurement.

STAT
STAT Titrations.


DET

Command for Dynamic Equivalence Point Titrations (

DET

).

Principle

With this command titrations with dynamic incremental reagent addition are car-

ried out. The volume increments vary as a function of the slope of the curve. An at-
tempt is made to achieve constant measured value alterations with each reagent
addition. The optimal volume for dosing is determined from the measured value
alterations of the previous reagent additions. Measured value acceptance is drift-
controlled (equilibrium titration) or after a waiting period.

Note

As the reagent addition in

DET

depends on the measuring data, the titration cur-

ve should not vary too much from an S-shaped curve.
