Product Description
Whatman diamond series TLC Plates exhibit gem-like qualities of hardness and reflectance. These technologically advanced glass-backed plates facilitate dipping and spraying and will not crack or flake. They allow you to perform scanning densitometry with the lowest noise backgrounds for maximum range in detection. The smooth surface of the plates prevents ripples from interfering with scanning or development. The plates will withstand most solvent systems and any applied developing reagent without silica falling off the plate or reacting with reagents. They can be charred to 180 degree C with cupric acetate/phosphoric acid reagents. Because 85 percent of all TLC users employ fluorescent plates, diamond series offers the best for UV quenching and visual work. All plates are silica gel with UV-254 fluorescent indicator and are available with channeling and a linear preadsorbent spotting area for faster, more accurate sample application. The 60 angstrom pore, 450 m sq/g surface area provides optimum characteristics for most clinical, educational and general analytical applications. Fast development of spots with excellent resolution makes the Diamond Series plates very suitable for screening and toxicology work; they are ideal for the analysis of micro samples.
