Rtx®-PCB Columns (fused silica)
(proprietary Crossbond® phase)
• Unique polymer for PCBs analysis by GC-ECD or GC-MS.
• Good results for other semivolatiles.
• Low polarity; inert to active compounds.
• Stable to 340 °C.
*Maximum temperatures listed are for shorter length columns. Longer columns may have a different maximum temperature.
