Deactivation Protocols

Introduction

Dynamic Adsorbents, Inc. aluminas are unique products; e.g., Super I, Std Act I, etc: high activity alumina is useful for eluting polar samples in nonpolar solvents, and for the purification of solvents. Lower activities of alumina can readily be obtained by the addition of polar media, especially water. Thus, each problem can be resolved via the adjustment of the sorption system, as required for each problem.

Deactivation Behavior

By the following procedures below, it is relatively easy to obtain the desired activity.

Alumina type super I I II III IV V
Super I -A,B,N 0 1 4 7 10 19% Water Added
Std Act I - A,B,N N/A 0 3 6 10 15% Water Added

A = Acid, B = Basic, N = Neutral

Special Features

Super I aluminas are twice as effective as compared to Standard Activity I. Super I does not have to be deactivated in steps. By following the appropriate deactivation curves, deactivation can be achieved in minute
