Water-based gas purge microsyringe extraction coupled with liquid chromatography for determination of alkylphenols from sea food Laminaria japonica Aresh.

Highlights: [•] We have developed a new water-based gas purge microsyringe extraction. [•] Organic-free sample pretreatment technique does not need drying process. [•] The extracts are directly submitted into the LC analysis. [•] Sample treatment is completed within 5min with high recovery and precision. [•] This technique is suitable for ionizable volatile and semivolatile compounds. [ABSTRACT FROM AUTHOR]
