NEUROSYIL Phenyl UPLC Columns: 100*A are engineered for enhanced selectivity through π-π interactions, ideal for aromatic and structurally similar compounds. Featuring a phenyl bonded phase on high-purity silica with 100Å pore size, these columns deliver excellent resolution, peak symmetry, and retention consistency. Suitable for pharmaceutical, biochemical, and complex organic compound analysis, they offer unique separation capabilities where traditional C18 or C8 phases may fall short.
