Agilent ZORBAX Eclipse PAH Column Specifications and Options
 
ZOBAX Eclipse PAH
Agilent ZORBAX Eclipse PAH packing is a polymeric C18 bonding designed to provide the high level of shape selectivity needed for PAH separations. It uses Eclipse Plus silica as its base silica. It provides high resolution separation of 16 PAHs in EPA Method 610. Each batch of materials is specifically tested with PAHs for maximum reproducibility.

polycyclic aromatic hydrocarbons in water, soil and food, fat soluble vitamins (alternative) EPA 610 Start with 5% methanol or acetonitrile in water as the initial solvent, and 100% methanol or acetonitrile as the final solvent. We recommend adding 0.1% formic acid in both A and B bottles. If using LC/MS, we recommend starting with 5 - 10 mM ammonium formate, ammonium acetate, ammonium hydroxide, 0.1% acetic acid or 0.1% formic acid. We recommend against using ammonium bicarbonate.
