The plate is highly pure and exhibits minimal background, even with middle-polar solvent systems. Ideal for advanced pharmacopoeia applications, this high-performance plate keeps separations free of contamination. Its separation performance is an exact match to the related HPTLC plate product. Based on the proven HPTLC 60 F254 plate, the HPTLC premium purity plate comes carefully wrapped in a special, plastic-coated aluminum foil. This prevents plasticizers (such as phthalates) from leaving deposits. Without the foil, the plasticizers could appear as an “unknown extra zone” when mid-polar solvent systems (such as toluene/ethyl acetate (95/5)) are in use, and they could be stained by derivatization reagents (such as anis aldehyde).
