Exsil 300 PAH is a specialized 300 Å wide-pore silica stationary phase developed for the high-resolution separation of polycyclic aromatic hydrocarbons (PAHs) in reversed-phase HPLC. Designed to enhance π–π interactions and shape selectivity, this phase provides optimized retention and resolution for structurally similar aromatic compounds, including regulatory PAH priority pollutants.
The tailored surface chemistry of Exsil 300 PAH promotes strong and selective interactions with aromatic ring systems, enabling precise discrimination of isomeric PAHs and closely related polyaromatic compounds. The 300 Å pore structure ensures efficient mass transfer and consistent chromatographic performance, even for higher molecular weight PAHs and complex environmental samples. Built on high-purity, spherical silica particles, Exsil 300 PAH offers excellent mechanical stability, reproducible retention times, and long column lifetime. The phase is fully compatible with common reversed-phase mobile phases and gradient conditions, making it ideal for environmental analysis, food safety testing, petrochemical applications, and regulatory compliance laboratories.
Exsil 300 PAH combines wide-pore silica technology with optimized aromatic selectivity – delivering precise, reproducible, and high-resolution PAH separations for environmental and industrial analytical applications.
