General Starting Method

Strata Screen-C GF Strong Cation-Exchange

Strata Illustrated Tube

1 mL Methanol
1 mL Acidified Water
Pretreated sample (acidified)
Wash 1
1 mL 0.1 N HCl in Water
Wash 2
1 mL 0.1 N HCl in Methanol, dry under vacuum for 2-5 min
1 mL 5 % NH4OH 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.
