Stick the column in the freezer overnight, then use the reamer to push out the copper. It works surprisingly well!

Subject: [ISOGEOCHEM] Removing reduced copper
just a quick question in the hope of saving costs:
does anyone know an easy way to remove the oxidised copper from the quartz column; so that the quartz column can be re-used?
