PAHs (Polycyclic Aromatic Hydrocarbon) are considered priority pollutants and the analysis of these potentially carcinogenic compounds in water, air, soil and food. The Ultisil PAH columns separate all of the 16 PAHS in EPA method 610 quickly (less than 30 min) with high resolution. The Ultisil PAH columns is silica based columns for PAHs analysis with best peak shape.
