Premium Purity HPTLC Plates
Premium purity HPTLC plates are optimized for high-performance, completely contamination-free separations, such as demanding pharmacopoeia applications. These highly pure plates exhibit minimal background, even with medium-polar solvent systems.
Based on our proven 60 F254 HPTLC plate, premium purity plates are carefully wrapped in plastic-coated aluminum foil. This prevents deposition of plasticizers (such as phthalates), which could appear as unknown extra zones when using medium-polar solvent systems, such as toluene/ethyl acetate (95/5). Furthermore, it avoids staining by derivitization reagents, such as anis aldehyde. The separation performance of each premium purity plate is identical to the corresponding HPTLC plate.
