ITEM #: 7158749
These plates allow users to quickly and easily apply any kind of sample, even large volumes of diluted samples. EMD Milliporeconcentrating 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...
