Optimized for gravity flow, this sorbent offers hydrophobic selectivity from a C8 phase and strong cation-exchange properties for the extraction of basic drugs from biological matrixes. Offers the selectivity of Screen-C in a gravity flow particle size for viscous samples.

1, 3, and 6mL Tubes

Giga Tubes (12-150mL Tubes)

| Condition  1 mL Methanol | 
| Equilibrate 1 mL Acidified Water | 
| Load 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 | 
| 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.
