Abstract
Liquid chromatography separation columns can be protected from contamination with particulate and dissolved contaminants by the use of a thin protective pad which removes contaminants from a sample stream prior to separation of the sample on the separation column. The protective pad may be in the form of a guard disk positioned inline or directly contacting the separation column.
