During this area we consider the standard plumbing needed to shift the cellular stage from the column and also to inject the sample in the mobile section.

To attenuate these issues we area a guard column ahead of the analytical column. A Guard column usually includes a similar particulate packing material and stationary phase as being the analytical column, but is noticeably shorter and less expensive—a duration of 7.five mm and a cost just one-tenth of that for that corresponding analytical column is normal. Mainly because they are meant to be sacrificial, guard columns are changed routinely.
