A robust and precise chomatographic method for the baseline resolution of RRR-α-tocopherol from its stereoisomers was acheived. A robust and precise chomatographic method for the baseline resolution of RRR-α-tocopherol from its stereoisomers was acheived. Pesticides are chemicals used mainly to protect plant crops in order to increase their production efficiency and quality. Switchable-solvent homogeneous liquid-liquid microextraction was optimized using a Box-Behnken experimental design and validated on a gas chromatography ma
