5 Determination mode
5.1 Determination mode overview
Determination mode features
The program part "Determination" is used for quantitative volt-
ammetric analysis of inorganic and organic substances. It com-
prises nine different measurement modes and the possibility for
stripping techniques. Quantitative evaluation can be performed via
standard addition or calibration curve.
The peak evaluation is automatic, various functions
(linear, poly-
nomial, horizontal and exponential) can be selected for the baseline
approximation. In case of asymmetric peaks, there is a possibility to
evaluate only the front or rear peak half.
Peak evaluation and result calculation are documented in an in-
dividually compilable report which can also contain voltammo-
grams and calibration curves.
The parameters of the voltammetric analysis are stored in a method
file. The method loaded into the working memory is the working
method which is used for performing new determinations. The
determination method is the method which was used for the
recording of the loaded determination and which is stored together
with the measurement data in a determination file.
