Precautions
● Keep the resin at a temperature of 5~40℃ when storing/transporting;
● If exposure to the air or caused water loss, cannot be directly rinsed into water, but can be soaked in
ethanol to recover its moisture and then wash it with water.
● Before resin-loading, the columns should be cleaned to prevent harmful substances;
● The feed liquid should be cleaned, filtered before entering the resin column to avoid contamination;
the resin should be desorption & soaked in salt solution (＞10%) to avoid bacterium;
● Do not mix resin with strong oxidants, as it may cause explosive reaction.
