Quantification of liposoluble micronutrients in large-scale vegetable oil samples is urgently needed, because their health benefits are increasingly emphasized. However, current analytical methods limited to either labor-intensive preparation processes or time-consuming chromatography separation. In this work, an online matrix separation strategy for direct, rapid, and simultaneous determination squalene, tocopherols, phytosterols walnut (WO) was developed on the basis lipid class mode...
Summary A new mixed C18-SCX SPE column and gas chromatography-mass spectrometry have been used for determination of six β2-agonists residues in pig's liver. After hydrolysis, the were extracted with 6:4 (v/v) ethyl acetate-isopropanol then cleaned on a commercial mixed-adsorbent solid-phase extraction column. The eluted solution was analyzed by (GC-MS) quantified external standard method. Sample pre-treatment GC-MS conditions critically examined. linear range 0.005–2.00 mg L–1 correlation...
