Mixed-mode SPE is a sample clean-up technique for LC-MS analysis. Selecting a mixed-mode SPE sorbent can be challenging, requiring a good understanding of the sorbent/analyte chemistry. In addition, it involves accurate and precise pipetting steps. This protocol demonstrates a rapid and robust Andrew+ automated mixed-mode SPE sorbent selection method using the Oasis 2x4 sorbent selection plate.
