InertCap ProGuard

 

InertCap ProGuard is a "guard column built-in" analytical capillary column.When analyzing samples high in matrix such as food, the guard column traps foreign substances and protects analytical column.By cutting the edge of the guard column,a longer analytical column life can be obtained.Also InertCap ProGuard acts as a retention gap column.The guard column is inert, therefore there is no need to worry when analyzing highly adsorbtive compounds.There is also no need to worry about leakage as there is no connector union used.* Refer to a chapter "How to Use Capillary Columns Better" for more details about retention gap.
