摘要：

Base-line perturbations, eigenzones, are generated in a high-performance liquid chromatographic (HPLC) column by sudden pressure variations if particular binary eluents are used. The proposed interpretation of the shape of these eigenzones allows the semiquantitative evaluation of the packing density distribution along the column. Common HPLC equipment allows the necessary experimental data to be obtained, and their evaluation is simple and straightforward. However, the correction of eigenzones for spreading is necessary in order to draw more reliable, quantitative conclusions.
