Starting Method

Strata NH2 – Weak Anion-Exchange

Condition 1 mL Methanol
Equilibrate 1 mL Water, pH 6-7
Load Pretreated sample, pH 6-7
Wash 1 1 mL 25mM Ammonium Acetate Buffer, pH 6-7
Wash 2 1 mL Methanol, dry under vacuum for 2-5 min
Elute Any Acid 1 mL 5% NH₄OH in Methanol
Elute Weak Acids 1 mL 5% Formic Acid in Methanol

Based on 100 mg/1 mL sorbent mass. The above is a convenient starting point for SPE method development, further optimization may be required to tailor the method for your specific extraction needs.
