Phenomenex Strata SCX Solid Phase Extraction (SPE)

Ion-Exchange Solid Phase Extraction (SPE) Sorbent

A benzene sulfonic acid group is bonded to the surface of the silica particle, giving strong cation-exchange selectivity.

• Extraction of 1 °, 2 °, and 3 amines

Phenomenex: Strata SCX

• Surface Area (m²/g): -
• Separation Mode: Ion Exchange
• Particle Size: 55
• Recommended Use: Extraction of weakly basic compounds

Starting Method

Strata SCX – Strong Cation-Exchange

• Condition: 1 mL Methanol
• Equilibrate: 1 mL Acidified Water
• Load: Pretreated sample (acidified)
• Wash 1: 1 mL 0.1N HCl in Water
• Wash 2: 1 mL 0.1N HCl in Methanol, dry under vacuum for 2-5 min
• Elute: 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.
