What is Strata® PAH?

Strata PAH is a proprietary SPE sorbent that is specifically designed for the extraction of polyaromatic hydrocarbons (PAHs) without co-extracting humic acids from aqueous based samples.  Conventional C18 SPE methods lead to co-extraction of humic acids, which can interfere with subsequent analysis.  Strata PAH selectively extracts PAHs and simultaneously removes humic acids.  See TN-0042 for method details.
