in a gaseous phase chromatograph, is the column continuosly fed with carrier gas or only during analysis?

usually since the materials in the column are oxygen sensitive gas flow is maintained as long as the column is installed in the GC. If removed, the ends of the column are capped (sealed, closed, etc) to prevent oxygen damage
