WAX SPE cartridge extraction of weak acids

WAX SPE Protocol for Weak Acid Extraction

Leave a Comment / WAX SPE Cartridges / By /

WAX Sorbent Chemistry Overview WAX (Weak Anion eXchange) SPE sorbents represent a sophisticated mixed-mode extraction technology designed specifically for strong acidic compounds. Unlike traditional single-mode sorbents, WAX employs a dual retention mechanism combining both ion-exchange and reversed-phase interactions. This innovative approach provides superior retention for strong acidic analytes, particularly those with pKa values below 1,
