| pubmed-article:12541809 | pubmed:abstractText | Domoic acid in shellfish samples was determined by HPLC with DAD/UV detector at 242 nm. Samples were extracted with methanol-water followed by clean-up of the extracts with strong anion exchange solid phase extraction cartridge(3 mL LC-SAX). Zorbax SB-C18 column, 150 mm x 4.6 mm i.d., and mobile phase of acetonitrile-0.1% aqueous trifluoroacetic acid(13:87, V/V) were used for the assay. The quantitative analysis was performed with external standard. The calibration curve of domoic acid was linear in the range of 1.0 m/L-25.0 mg/L and the detection limit was ca. 0.2 microgram/g. | lld:pubmed |
