Strata Screen C-GF Solid Phase Extraction (SPE) sorbent is a mixed-mode large pore sorbent used for clean up of drugs from viscous samples
Strata Screen-C GF SPE Products
Strong Cation-Exchange Solid Phase Extraction Sorbent (SPE)

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.

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.
