4. viva «Method»
viva software includes three method templates for CVS
analysis with a semiautomated system.
• Brightener determination (CVS, MLAT), semiautomated
• Conditioning (Cu VMS), semiautomated
• Suppressor determination (CVS, DT), semiautomated
The templates already establish the basic sequences for the
different applications and the use of 800 Dosinos for
automatic dosing as well as the calculation of the result.
However certain commands and settings have to be
adapted to the used hardware and the requirements of the
specific application.
For a step by step description please see the Tutorial
chapter «5.2 Methods for the semiautomated
determination».
The following commands have to be adapted:
4.1. Method run
4.1.1. Measuring commands
Such as
3.4. Solutions
Solutions that should automatically be dosed have to be
defined in the viva «Configuration» and need to be
assigned to the Dosing Unit which is used for the dosing.
The following table shows the solution names and assigned
Dosing Units as used in the viva method templates.
Page 5 of 7
• Assign the 894 Professional CVS instrument to be used
on the tab «General/Hardware».
• Adapt the measuring parameters on the tabs «Pre-
treatment», «Sweep», «Post-treatment» and
«Potentiostat» according to the requirements of the
application. These parameters can be found in separate
application documentation.
Application Bulletin 401/1 e
Installation instruction for 894 Professional CVS semiautomated
4.1.2. Dosing commands
Such as:
• Define the volume of solution that should be dosed
when this command is due.
Such as:
• Define the volume of solution that should be dosed
when this command is due.
• Assign the Dosing Unit that should be used to run this
command.
Such as:
• On the tab «General/Hardware» assign the 894
Professional CVS instrument to which the 800 Dosino is
connected.
On the tab «Database» the database is defined where
determinations should be stored. By default viva database
is used.
On the tab «Report» a report template for an automatic
printout can be defined. By default no printout is defined.
5. Operation
5.1. Suppressor determination
5.1.1. Manual operation
• Dosing Unit «894/D1 50mL VMS» connected to Dosino
1 has to be prepared with VMS.
• Dosing Unit «894/D4 2mL Std or sample» connected to
Dosino 4 has to be prepared with suppressor standard
solution if a calibration is recorded or with plating bath
sample for the determination.
5.1.2. Workplace
4.2. Evaluation
Settings regarding evaluation and documentation of the
determination are located in the «Evaluation» part of the
method. The templates already include all necessary
settings to determine brightener or suppressor concentration
in an acid copper bath. If modifications however should be
necessary, here is where important parameters are found:
4.2.1. Substances
In the «Substances» part settings for peak recognition and
baseline parameters are defined.
4.2.2. Standards
In the «Standards» part the concentration of the used
standard solution is defined.
4.2.3. Calibration
In the «Calibration» part the calibration method, such as DT
or MLAT, is defined as well as the regression type.
• Select sample type S
TANDARD to run a calibration in the
«Run» window of the «Workplace». For a determination
sample type S
AMPLE has to be selected.
• No «Sample amount» needs to be defined in the «Run»
window on the «Workplace», since addition volumes for
the standard and the sample are defined in the method
commands ADD
STD and ADD SAMPLE DT.
5.1.3. Course of events
• The execution of calibration or determination by dilution
titration is controlled by the 894 Professional CVS and
viva.
• Dosino 1 automatically doses the VMS and Dosino 4 is
used for the automatic addition of suppressor standard
or plating bath sample.
4.2.4. Results
In the «Results» part on the tab «Results» the substance is
selected for which the concentration should be calculated
and displayed.

5.2. Brightener determination
5.2.1. Manual operation
• Dosing Unit «894/D1 50mL VMS» connected to Dosino
1 has to be prepared with VMS.
• Dosing Unit «894/D2 2mL Brightener» connected to
Dosino 2 has to be prepared with brightener
concentrate.
• Dosing Unit «894/D3 2mL Suppressor» con nec ted to
Dosino 3 has to be prepared with suppressor
concentrate.
• The correct «Sample amount» has to be pipetted into
the measuring vessel when requested.
5.2.2. Workplace
• Select sample type S
«Workplace» to run a determination.
• Define the volume of sample used for the determination
under «Sample amount» in the «Run» window of the
«Workplace».
AMPLE in the «Run» window of the
water. Otherwise elemental copper can be formed or
additives can precipitate between the valve disk and the
distributor disk or in the tubings. A blockage can damage
the 800 Dosino. Emptying the cylinder and filling it with
water is sufficient to prevent a blockage.
6.2. Storing electrodes
When the electrodes are not used (during the night, over the
weekend) the electrodes should be thoroughly rinsed.
Working and auxiliary electrode can either be stored in
deionized water or dry. The reference electrode should be
stored separately in a vial filled with deionized water (KCl
solution, in case KCl is used as bridge electrolyte), so that
the reference electrode immerses at least to the rim of the
electrolyte vessel.
6.3. Waste bottle
The waste bottle must not be closed completely. For
pressure balancing in the waste bottle, keep at least one
opening unsealed. Overpressure would lead to a
malfunction of the 800 Dosinos.
5.2.3. Course of events
• The execution of the determination by modified linear
approximation technique is controlled by the 894
Professional CVS and viva.
• The intercept solution is automatically prepared at the
beginning of each determination, by dosing VMS from
Dosino 1 and suppressor concentrate from Dosino 3.
• After the determination of the intercept value, a window
will pop up prompting to add the sample on top of the
intercept solution. The ex act s ampl e volu me has to be
pipetted manually through the pipetting opening of the
894 Professional CVS.
• Standard addition is carried out automatically with
brightener concentrate from Dosino 2.
6. Remarks
6.1. Storing dosing units
When the dosing units are not used (during the night, over
the weekend) the dosing cylinder has to be rinsed with
