Description
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
