Paper chromatography (PC) is the oldest chromatographic technique. Like other chromatographic applications, separation is based upon the partition of the material mixture, which is to be separated, between two immiscible phases.
While the chromatographic paper is, strictly speaking, only the carrier for the liquid mobile phase, the properties of the paper do, in fact, have considerable influence on the quality of the separation.
The most important characteristics of chromatographic papers are the weight (g/m2), the thickness (mm) and the migration distance.
When specifying the migration distance, it is common practice in the paper industry to apply the Klemm method. This method indicates the extent of dampness of a 15 cm wide paper strip (dipped in 20 °C dist. water) after 10 minutes. You will, however, frequently find the migration distance of chromatographic paper specified in mm/30 min.
