As species in Fish Tissue

First method 1 g of sample was extracted with water/methanol (1/1 v/v) (3 X 20 mL) by mechanical stirring the extract was evaporated, diluted with 10 mL water, filtered (0.2 pm filter), passed on a Cis Sep-Pack cartridge and stored in a glass flask at 4 °C in the dark. Separation was by anion exchange LC (Hamilton PRP X 100) in isocratic mode (phosphate). Hydride generation was carried out (using 1% NaBH4 in NaOH/HCl) followed by QFAAS detection. [Pg.132]

First method a subsample of 1 g was ultrasonically extracted with water/ methanol (1/3 v/v) (5 x 20 mL) the extract was evaporated and diluted with [Pg.132]

20 mL water. Clean-up was carried out by filtering on a Fluorisil Sep-Pack cartridge. The extract was stored in a brown glass flask at 4 °C in the dark. Separation was by ion-pair LC (Hamilton PRP 1) in isocratic mode (TBAP/ Na2HP04/Me0H). Final detection was ICP-MS of mass 75. [Pg.133]
