WebIon exchange SPE can be used for compounds which are charged when in a solution. Finally in mixed-mode SPE, two diﬀ erent functional groups on the same sorb-ent are used. Isolation involved in both reversed phase and cation exchange is a general example for this type of SPE (Majewska et al., 2008; Thurman and Mills, Web1. Prepare SPE stationary phase for amino acid binding adding by equilibrating with 1 equivalent of methanol (200 µL for SOLAµ 2 mg, or 500 µL for SOLA 10 mg). 2. Wash SPE stationary phase with 1 equivalent of water with 1% formic acid. 3. Acidify sample containing amino acids, for example dilute 500 µL sample with 500 µL 1% formic acid.
