5 Titrations
5.1 Dynamic equivalence point titration (DET)
Dynamic equivalence point titration is a titration mode for all standard
titrations. The reagent is added in variable volume steps. The volume
increments vary as a function of the slope of the curve. An attempt is
made to achieve constant measured value alterations with each dosing.
The optimal volume for dosing is determined from the measured value
alterations of the previous dosings. Measured value acceptance is driftcontrolled (equilibrium titration) or after a waiting time. Equivalence points
are evaluated automatically.

5.2 Monotonic equivalence point titration (MET)
Monotonic equivalence point titration is a titration mode for titrations
with relatively high signal fluctuations or suddenly occurring potential
jumps and for slow titrations or slow-response electrodes. The reagent is
added in constant volume steps. Measured value acceptance is drift-controlled (equilibrium titration) or after a waiting time. Equivalence points are
evaluated automatically.

5.3 Endpoint titration (SET)
Endpoint titration is a titration mode for rapid routine determinations to a
preset endpoint (e.g. titrations in accordance with special norms) and
titrations for which reagent overflow must be avoided. The titration termination at the endpoint takes place either drift-controlled or after a waiting
period. The volume dosed until the endpoint is used for calculating the
content of the sample.

5.4 Water determination according to Karl Fischer (KFT)
Karl Fischer Titration is a method for volumetric water determination. Conditioning is carried out automatically both before and after the actual titration. The reagent dosing is controlled in such a way that a predefined
endpoint is reached as quickly and as accurately as possible. The volume
steps and the rate of reagent dosing are regulated by the difference
between the current measured value and the predefined endpoint. This
means that titration is performed more slowly in the control range and
that smaller volumes are added. The titration is stopped at the endpoint
either drift-controlled or after a waiting time. The volume dosed until the
endpoint is used to calculate the water content of the sample.

5.5 Endpoint titration with constant maintenance of the measured value (STAT)
The pH STAT titration is the one most frequently utilized. Reagent is added
until a preset measured value (control point) has been reached. This control point is kept stable by continuously titrating off the substance set free
by the reaction with the reagent. The STAT titration keeps the control
point constant until the preset stop criterion has been reached. The STAT
titration is applied, for example, in analysis of enzymes. The dosing rate
resulting from the the control point being kept stable provides insight into
the activity of an enzyme.

guideline 21 CFR Part 11, then you must use the functions of the user
administration. Additional information regarding the requirements of the
FDA guideline can be found in the Titrando Compliance Guide.
NOTE
If you work with the login function activated, then the user administration is accessible only for users with administrator rights. This means
that you must ensure that at least two users have administrator rights
so at least one of them will be available. Keep the access rights for a
user with administrator rights in a safe place so that they are accessible
in an emergency.

storage medium for each user. A check can then be made at the time of
login as to whether or not the user does exist and whether or not he or
she is working in the expert dialog or in the routine dialog. After a successful login the routine dialog settings stored on the card are loaded.
NOTE
In addition to the user name, the current routine dialog settings are
also stored in this identification profile. This means you can define userspecific routine dialog settings for each user. However, you must configure them (see "Configuring the routine dialog", page 26), before
you create the identification profile.

Main dialog: System ▶ Titrants
This chapter describes how you can create a list of titrants used in the system. Titrants can be used in intelligent buret units or in non-intelligent
buret units. Intelligent buret units have a built-in data chip on which the
data for the titrant is stored. This data is automatically read out during
attachment and entered in the titrant list.
The titrant list can contain a maximum of 30 titrants. The following data is
specified for each titrant:
￭ Designation
￭ Cylinder volume
￭ Type
– EU: exchange unit without data chip
– IEU: exchange unit with integrated data chip
– DU: dosing unit without data chip
– IDU: dosing unit with integrated data chip
￭ MSB connector of the dosing device/control device (only when
exchange unit/dosing unit is attached)
Titrants in exchange units/dosing units with integrated data chips are
depicted in green lettering.
The following titrant data is stored in the titrant list:
￭ Name
Each titrant in the system is identified by its unambiguous name.
