Low‐noise, reproducible UV/VIS spectra up to the 7th derivative can now be plotted on‐line with the aid of a novel analog computer unit. Optimum resolution is usually achieved up to the 4th derivative: all shoulders, terraces, and points of inflection of unipolar signals are generally transformed into bipolar signals. Numerous applications exist.
