CHROMABOND® SiOH-H₂SO₄/SA is a combination phase for SPE analysis of PCBs.

• SiOH-H₂SO₄ phase for oxidation of accompanying compounds to ionic and/or polar compounds
• SA cation exchanger for removal of ionic and sulfur-containing compounds

Application: PCB extraction from oil-contaminated solids or oil samples (hexane extract); also applicable in accordance with DIN EN 12766-1 and DIN EN 51 527.

This combination column is generally used together with a SiOH column. Both columns together are available as Kombi-Kit PCB.
