Ready-to-use layers for HPTLC glass plates In addition to TLC ready-to-use layers with standard silica coating we manufacture high performance ready-to-use layers (HPTLC) under the name “Nano silica”. The adsorbent, as in HPLC, is narrowly fractionated. We use mean particle sizes of 2 – 10 μm.Key features of HPTLC plates: - sharper separations due to small particle size and narrow fractionation. Theoretical plate heights (h values) are considerably smaller than those of the standard TLC plate. In addition diffusion and – as a consequence – band broadening are much lower. - shorter developing times and shorter migration distances. After only a few centimeters an optimal separation is achieved. - smaller samples of 0.01 – 0.1 μl (10 – 100 nanoliters). The samples applied are considerably sm...Read more
