Chromatographic Properties
Developed specifically for challenging analyses of polycyclic aromatic hydrocarbons (PAHs).
The Pinnacle® II PAH stationary phase incorporates a proprietary C18 bonding that enables
unique shape selectivity to baseline-resolve all 16 PAHs listed in U.S. EPA Method 610 plus two
other routinely analyzed PAH compounds. Every lot of Pinnacle® II PAH bonded phase
material is tested to ensure baseline resolution of the Method 610 PAHs using a simple water/
acetonitrile mobile phase gradient. Further, because we make Pinnacle® II PAH columns using
our own silica, we have greater control over quality and reproducibility. If you are analyzing
PAHs using HPLC, Pinnacle® II PAH columns are a reliable, cost-effective choice.
