ISOLUTE¢ç PAH SPE Columns for Extracting PAHs
ISOLUTE PAH SPE columns are designed to extract PAHs from water samples containing polar interferences such as humic acids. The layered column contains a NH2 layer above a C18 sorbent bed. Polar interferences are retained on the NH2 layer during extraction, but are not eluted with the PAHs, giving a pure extract for analysis.
