On the Standard Ion Chromatography channel separation column, are the frits and guard disc on the inlet of the Lachat QC8000/8500 replaceable?
Replacing the green guard in the column
Yes, the frits going into the column are replaceable. The tan frit is Product # 28110. The green guard is Product # 28132. The Frit is designed to be replaced when clogged and can be considered a consumable item. We do not recommend replacing the green guard in the column unless it is a last ditch effort and the column is expected to be replaced soon anyways, as removing the guard can be difficult and can cause damage to the column. Attached is an image of both the frit and disc.
