Virtual instrument for potentiometric stripping analysis

The construction of an original computer-controlled instrument for potentiometric stripping analysis (PSA), optimized for the least expenses and maximum data acquisition rate, is described. Some unusual features, like the error compensation of A/D differential linearity and the automatic adjustment of optimal data sampling frequency, have been implemented. The main advantage of the virtual instrument consists in its maximum function versatility achieved by controlling software and in an easy way for introducing new applications.
