Indispensable in PAH trace analysis
LiChrospher® PAH is a highly efficient and selective HPLC column especially designed for the high resolution separation of 16 PAH (polycyclic aromatic hydrocarbons) according to EPA 610 and 550 + benzo(e)pyrene + perylene.
Polycyclic aromatic hydrocarbons (PAH) are derived from organic material by pyrolysis or incomplete combustion. The main sources are the exhaust fumes of private and industrial furnaces, car exhaust and tobacco smoke. Since some PAH are carcinogenic, their determination is of great importance. LiChrospher® PAH is based on a RP-18 silica gel specially modified to achieve highly resolved PAH separations.
LiChrospher® PAH can be used for both the isocratic separation of 6 PAH according to the German DIN method and the gradient separation of 16 PAH according to EPA + benzo(e)pyrene + perylene.
LiChrospher® PAH achieves excellent results for the separation of 16 PAH (EPA 610) + benzo(e)pyrene + perylene:
- Baseline separation at 25°C or 20°C by gradient HPLC (esp.: benzo(e)pyrene, benzo(b)fluoranthene and perylene)
- Programmed fluorescence detection
- First eluting PAH (naphthalene) at ca. 10 minutes
- Separation within 30 minutes
- Simple eluents and gradients.
