GC COLUMNS | HIGH-PERFORMANCE Rxi® COLUMNS
Rxi®-PAH
Rxi®-PAH Columns (fused silica)
(midpolarity proprietary phase)
• Ideal for EFSA PAH4 analysis—separates all priority compounds: benz[a]
anthracene, chrysene, benzo[b]fluoranthene, 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.
• 360 °C thermal stability allows analysis of low-volatility dibenzo pyrenes.
