When should you load your concentrated pigment solution onto your column in column chromatography? Options: When you still have a few centimeters of eluent on top of the sand layer. When the eluent is just level with the sand layer. As soon as you can, as it will decompose quickly in the light. When the eluent has all dripped out of the column.
