Description of Normal Phase Silica Solid Phase Extraction (SPE) Cartridges

Silica solid phase extraction (SPE) cartridge is an unbonded silica gel packing. It is a polar positive phase adsorbent that retains polar compounds in the sample, especially structurally similar polar compounds.

Characteristics of Normal Phase Silica Solid Phase Extraction (SPE) Cartridges

Very strong polarity retention
High load capacity
Separable structurally similar polar compounds


Specific surface area: 480 m² / g
Particle size: 40-75μm
Average pore size: 70Å
