PA Marshall, JM Vandepeer, I Pant, VC Trenerry, P Scheelings, DR Buick. The development and evaluation of secondary food reference materials for the determination of cholesterol, fatty acids and selected water-soluble vitamins in foods. Food Chem 58 269-276, 1997. [Pg.476]

FIGURE 18.3 Extracted ion current profiles of the water-soluble vitamins detected in a green kiwi extract (see reference [138] for the details). The LC—SRM (standard reference material) chromatogram was acquired by a high-flow ESI source (TurboIonSpray source). Each analyte was identified on the basis of the retention time, the two selected SRM transitions and their relative abundance. Only the most intense SRM ion current is reported in the figure.
