Welch Materials Ultisil PAH Columns

Ultisil PAH column features a unique high-density bonding process with a high carbon load, delivering excellent chromatographic separation performance for polycyclic aromatic hydrocarbons (PAHs). It is fully compatible with EPA Method 610 for high-resolution separation of 16 PAHs. With strong spatial hindrance selectivity, it effectively separates mixtures of planar and stereostructural compounds.

Ultisil Series HPLC Columns are based on ultra-pure (purity > 99.999%) spherical and totally porous silica, unique bonding chemistry and proprietary surface modification techniques, producing excellent peak shape, column efficiency and exceptional lot-to-lot reproducibility. Ultisil column is the best choice for method development. owing to complete bonding chemistries and stable performance.

Features
