Sample Preparation
Additional SampliQ SPE Phases
SampliQ Alumina B (basic)
SampliQ Alumina B sorbents, with 50-200 µm particle size, can adsorb molecules by
interaction with the aluminum metal center, hydrogen bonding with the surface hydroxyl
groups, or ion exchange if the surface carries a charge. Washing with a basic solution results
in a net negative charge, allowing retention of certain compounds as cations on the surface
or by specific interaction with the center.

500 mg, 3 mL 50/pk 5982-4135
1000 mg, 6 mL 30/pk 5982-4160
Bulk 25 g bottle 5982-4182
SampliQ Alumina N (neutral)
SampliQ Alumina N sorbents, with 50-200 µm particle size, can adsorb molecules by
interaction with the aluminum metal center, hydrogen bonding with the surface hydroxyl
groups, or by ion exchange if the surface carries a charge. The neutralized surface allows
interaction with compounds whose heteroatoms are electronegative (e.g., N, O, P, S)
or with an electron-rich, highly aromatic structure.
