channeled glass plate:

Channel-plate with 19 channels help to prevent cross contamination by separating several samples. More samples can be separated on a plate, and spot areas can be more easily determined.

Kieselguhr zone for rapid sample application:



Because kieselguhr is completely inert towards a large number of compounds, the samples always form a narrow band at the interface of the two adsorbents, irrespective of shape, size or position of the spots in the concentrating zone (see figure). Separation then takes place in the silica layer.
