EMD* PLC Concentrating Zone Glass Plates

PLC plates are for applications involving higher sample quantities. They are based on the same proven EMD Millipore silica-binder technology as analytical TLC plates, however they allow loads of up to gram amounts. Samples are typically applied as a band across the whole width of the plate, and substances are detected almost exclusively by UV detection. The substances can be isolated by extraction after the spot has been scraped from the layer. PLC plates are perfectly suited for cleaning up synthetic reaction mixtures, natural products, plant extracts and biotech products.

The concentrating zone of preparative plates (PLC) is 4 cm in length. These concentrating zone plates are based on different adsorption properties of two adsorbents. The first is a large pore concentrating adsorbent where the samples are applied; the second is a selective layer for separation. Regardless of the spots shape, size, or position, the sample always concentrates as a narrow band where the two adsorbents overlap and where the separation starts. These plates allow users to quickly and easily apply any kind of sample, even large volumes of diluted samples.
