When Should You Use HLB Instead of Ion Exchange SPE?
1. HLB Sorbent Chemistry Hydrophilic-Lipophilic Balanced (HLB) sorbents represent a significant advancement in solid-phase extraction technology. Unlike traditional silica-based sorbents, HLB sorbents are constructed from a water-wettable copolymer that combines both hydrophilic and lipophilic retention mechanisms in a single polymeric structure. The fundamental chemistry of HLB sorbents involves a carefully engineered copolymer that provides balanced
