Strata-XL-A SPE Products
Large Particle Strong Anion Mixed-Mode Solid Phase Extraction (SPE)
A large particle, strong anion-exchange functionalized polymeric sorbent that allows for complete retention of acidc compounds with a pKa greater than 2, making 100% organic wash conditions possible. A 100% organic wash ensures that the maximum amount of interferences are removed from the target compound. The large particle format makes this sorbent ideal for processing large volumes or viscous samples.

Column
1mL Methanol
Equilibrate
1 mL Water, pH 6-7
Load
Diluted Sample pH 6-7
