Applicable for the determination of naphthalene, fluorene, phenanthrene, anthracene, fl uoranthene, pyrene, benz[a]anthracene, chrysene, benzo[a]pyrene in seafood tissues including fi nfi sh and shellfi sh. The method is expected to be applicable to alkylated PAHs and related compounds in similar matrices. Limits of quantitation were shown to be < 1ng/g.

Twister® / Stir Bar Sorptive Extraction (SBSE)

The GERSTEL Twister® enables efficient extraction of organic compounds from aqueous matrices based on Stir Bar Sorptive Extraction (SBSE). SBSE is a solvent-free extraction technique, which is significantly faster than most conventional extraction techniques. SBSE is up to 1000x more sensitive than SPME since the stir bar has significantly more sorbent volume and since it can extract, and concentrate analytes from, a much larger sample volume due to the efficient stirring.
