1.1 Purpose of program
« VA Computrace 2.0» is the name of the control software for the
PC-controlled 757 VA Computrace System for voltammetric ana-
lysis. This system consists of the following parts:
1.757.0010
VA Computrace Stand with accessories
3.757.1300 Add-on Board for PC or
6.5326.000 VA Computrace Interface
6.2135.010 Connecting Cable
6.6032.100 VA Computrace Software 2.0
For a detailed description of the hardware components of the 757
VA Computrace System see the
757 Hardware Manual.
This 757 Software Manual describes the features and operation
procedures of the 757 VA Computrace Software which comprises
the clearly arranged user interface with a task bar that can be
clicked for control of the instrument, method development and
the recording and evaluation of the voltammograms.
Depending on the objective, the 757 VA Computrace Software
can be used in
two different operating modes:
• The exploratory mode for qualitative analysis is suitable
for practice-oriented voltammetry training at universities,
technical colleges and in plants. It allows the user to apply
seven different VA measurement techniques and to compare
their results.
• The determination mode is used for quantitative analysis
of inorganic or organic substances. Calibration can be done
via standard addition or calibration curves. Signal evaluation
and concentration calculation are automatic. On completion
of the measurement, a report can be compiled to suit individ-
ual requirements and printed out. The most important meth-
ods for the determination of metals or other substances can
be called up directly. All curves appearing on the screen, i.e.
voltammograms and calibration curves plus the results can
be transferred to other Windows applications via the Windows
Clipboard. Data export in ASCII format is also possible.
