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.

- Chromatografie papieren moeten zeer zorgvuldig worden behandeld.

- Raak nooit met de vingers aan, omdat dit het oppervlak kan verontreinigen.

- Buig of buig niet scherp, omdat dit het capillaire effect verstoort (het is het beste om het plat op te slaan)

• Chromatography papers must be handled very carefully.
• Never touch with fingers as this will contaminate the surface.
• Do not bend or bend sharply, as this will interfere with the capillary effect (it is best to store it flat).

- Chromatografie papieren hebben een voorkeursvezeloriëntatie met hogere absorptie langs de vezels (met onze bogen 58 x 60 cm is de langere rand).

- Wij raden u aan om het te verplaatsen in de richting van de om een hogere absorptie te gebruiken

• Chromatography papers have a preferred fiber orientation with higher absorption along the fibres (with our bows 60 × 58 cm the longer edge).
• We recommend that you move it in the direction of the to use a higher absorption
