Chromatography post image

A technique using various sized columns and substrates to perform purification by Size Exclusion Chromatography (SEC), Cation Exchange or Affinity Chromatography. The photo shows a Protein A 5ml column that is showing signs of channeling. The darker brown colored sample can be seen seeping unevenly through the resin. When you have a channeling column you will not achieve optimal purification.
