Sample Preparation:

Sampleprep ID:	SP002992
Sampleprep Summary:	Briefly, 50 μL plasma spiked with 10 µL internal standard mixture and 10 µL BHT was blended into 380 µL methanol (75%). MTBE (1 mL) was added, and the mixture was vortexed for 30 min. Phase separation was induced by adding 250 µL H₂O. After incubation for 10 min at room temperature, the samples were centrifuged at 14 000 g for 10 min. The upper phase was collected and dried using a nitrogen evaporator. Ultra-performance liquid chromatography BEH C18 columns (1.7 μm, 100 × 2.1 mm i.d.) were used for chromatographic separations.
