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.

Thermo Scientific’s SOLA is the first fritless SPE product range. The proprietary manufacturing process involved in the production of SOLA eliminates issues that can be associated with conventional loose-packed SPE products such as settling and voiding in production or transportation, which can create phase channelling and packing irreproducibility. SOLA fritless SPE products combine the polyethylene frit material and the media components into a uniform sorbent bed, thus removing the need for frits. Thermo Scientific have now expanded their fritless SPE product range to include SOLAu plates. These are designed for bioanalytical and clinical research analysts who are working with reduced sample volume analysis or require pre-analysis sample concentration.
