TLC Channel Plates

Macherey-Nagel now offer TLC Channel plates (20 x 20cm) with 19 channels, which help to prevent cross contamination when separating several samples. More samples can be separated on a plate and spot areas can more easily be determined. In addition, channel plates provide a kieselguhr zone for rapid sample application. Since 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. Separation then takes place in the silica layer. This product was developed to be a direct alternative to the discontinued Whatman TLC channel plates.
