Guardian™: Integrated Guard Columns

Built-In Column Protection
  • 5 or 10 meter guard built directly into the analytical column in one continuous length of tubing
  • Provides the same inert column protection
  • Eliminates the possibility of leaks

Extend Column Lifetime Up to 20 %!
Impurities are trapped within the first 4-6 inches of the integrated guard section, allowing easy removal of contaminants by column trimming. The guard section of the column does not contain stationary phase, so separation is not affected!
