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
comprises six different measurement modes and the possibility
for stripping techniques. Quantitative evaluation can be per-
formed via standard addition or calibration curve.
The
peak evaluation is automatic, various functions (linear, poly-
nomial, exponential) can be selected for the baseline approxi-
mation. 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 determina-
tions. 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.
