Normal Phase (Polar)
- Average particle size of 45 µm and pore diameter of 60 Angstrom to reduce pressure drop and increase flow reproducibility
- Agilent’s trifunctional bonding process provides more stability over monomeric bonding
- Manufactured to Agilent’s rigorous quality standards in the USA, using the same processes and facilities that make our HPLC columns so reliable
SampliQ Amino (NH2) SPE products are based on irregular, silica gel (silica) particles. This dual purpose sorbent can act either as a polar phase or weak anion exchanger. When conditioned with a non-polar solvent, e.g., hexane, it can hydrogen bond with any molecule containing -OH, -NH, or -SH functional groups. In an aqueous environment with pH 7.8 or less, it can function as a weak anion exchanger.
Agilent Technologies products are intended for sale/shipment within the US only. International customers should contact their local Agilent Technologies distributor to place orders for Agilent Technologies products.
