EZ-Guard columns combine a FactorFour column with a built-in guard column.

• Lack of a column connection between the guard and analytical section results in a 100% leak-free column
• Features a unique uncoated and deactivated outlet section acts as an integrated transfer line

The absence of a stationary phase in the last part of the column significantly reduces background noise. The impact of water, oxygen or other polar or aggressive components that move through the end of the column at high temperature will also be greatly reduced.
