EZ-Guard GC Columns
EZ-Guard columns combine an Agilent J&W VF GC column with a built-in guard column. The first 5 or 10 m section of the column (depending on the configuration) is not coated with stationary phase, but has been deactivated. Eliminating the column connection between the guard and analytical sections ensures 100% leak-free performance.
