How Does an SPE Column Work?

Solid Phase Extraction (SPE) columns work through a four-step process that selectively separates target compounds from complex matrices:

1. Conditioning: The sorbent is activated with a solvent (typically methanol) followed by equilibration with a solvent matching the sample matrix to prepare the stationary phase.
2. Sample Loading: The sample is applied to the column. Target analytes interact with the sorbent while many impurities pass through.
3. Washing: Interfering compounds are removed using a solvent strong enough to wash away impurities but weak enough to retain analytes.
4. Elution: Target compounds are recovered using a strong solvent that breaks their interaction with the sorbent phase.

The mechanism depends on the sorbent phase chemistry:

  • Reversed-phase (C18, HLB): Hydrophobic interactions retain non-polar compounds
  • Normal-phase (Silica, Florisil): Polar interactions retain polar compounds
  • Ion-exchange (MCX, MAX): Ionic interactions retain charged molecules
  • Mixed-mode: Combines multiple interaction mechanisms for selective extraction
