Medium polarity phase ideal for separation of EFSA PAH4 priority compounds benz[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene. Resolves chrysene from interfering PAHs, triphenylene, and cyclopenta[cd]pyrene, and achieves complete separation of benzo [b], [k], [j], and [a] fluoranthenes. Temperature range: ambient to 360C. Unique, proprietary phase for PAH analysis in environmental methods as well as food safety testing.
