ISOLUTE¢ç Alumina (sorbent ref. 713 714 715)
Polar SPE

High activity, 50–200 ¥ìm particle size range alumina, available in acidic, neutral and basic surface pH options. The surface of the alumina can absorb molecules by interaction with the aluminum metal center, hydrogen bonding with surface hydroxyl groups, or by ion exchange if the surface carries a charge. The extent of these different interactions can be enhanced by control of the surface pH by treatment with acidic, basic or neutral solutions.

ISOLUTE AL-A
Acid washing results in a surface with decreased capacity for basic compounds. Compounds are retained by ion exchange with the positively charged surface or by specific interactions with the metal center.

ISOLUTE AL-N
Neutral surface allows interactions of the aluminum metal center with compounds whose heteroatoms are electronegative (e.g. N, O, P & S) or whose highly aromatic structure make them ¡°electron rich¡±. The adsorbent can be useful for retaining amines and aromatic compounds from either aqueous or non-aqueous solvents.

ISOLUTE AL-B
Washing this material with a basic solution results in a net negative charge. Cationic compounds are retained on the negatively charged surface or by specific interactions with the metal center.
