Strata-X-C solid phase extraction (SPE) sorbent is a polymeric strong cation exchange sorbent that can be used to cleanup basic compounds

Strata-X-C SPE Products

Strong Cation Mixed-Mode Solid Phase Extraction (SPE)

A strong cation-exchange functionalized polymeric sorbent that allows for complete retention of basic compounds with a pKa less than 10.5, making 100% organic wash conditions possible. A 100% organic wash ensures that the maximum amount of interferences are removed from the target compound.

Starting Method

For Bases with pKa ≤ 10.5

Column:
1 mL Methanol
Equilibrate:
1 mL Acidified Water
Load:
Diluted Acidified Sample
Wash 1:
1 mL 0.1 N HCI in Water (collect this fraction to analyze Polar Neutrals)
Wash 2:
1 mL 0.1 N HCI in Methanol (collect this fraction to analyze Neutrals/Acids)
Elute Bases:
2x 500 µL 5 % NH4OH in Methanol

Based on 30 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.
