SH-I-PAH Mid-polarity proprietary phase
Ideal for EFSA PAH4 analysis—separates all priority compounds: benz[a]anthracene, chrysene, benzo[b] uoranthene and benzo[a] pyrene.
Best resolution of chrysene from interfering PAHs, triphenylene, and cyclopenta[cd]pyrene.
Complete separation of benzo [b], [k], [j], and [a] fluoranthenes.
