Normal Phase Silica SPE Cartridges
Silica 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 SPE Cartridge
Very strong polarity retention
High load capacity
Separable structurally similar polar compounds
