Guard Columns - Retention Gaps
Guard columns consist of 5 meters of deactivated fused silica supplied with high temperature string. All guard columns are extremely inert and each is pretested.

Guard columns are useful in protecting your analytical column from harmful non-volatile contaminants that are commonly found in many environmental and industrial samples.

Attaching the guard column to the front of the analytical column using fused silica connectors, or a zero dead volume
union, will extend your column’s lifetime. The non-volatile contaminants are deposited onto the guard column.
