Phenomenex Zebron Z-Guard GC Columns

Protect and Extend Column Lifetime

• Individually QC tested to ensure the highest level of quality
• Extend column lifetime by preventing stationary phase damage
• Improve separation and peak shapes (especially early elutors)
• Improve sensitivity and accuracy of quantitative results
• Available as individual guard columns or as complete kits with connectors

To ensure that all Z-Guards are the highest possible quality, we individually test each one! The columns are attached to a reference Zebron ZB-5 column and are tested using our specially designed QC mix. We carefully monitor activity, bleed, and stability. This way, we are able to say with confidence that Z-Guards will provide the low activity and high quality your methods require.

Phenomenex: Zebron Z-Guard GC Columns: Using Z-guard columns

The most important aspect of a good seal is a good column cut.

• The column end should be square and smooth (like a straw). Any irregularities will cause leaks.
• Columns are long - repeat cutting until a good cut is achieved.
• Lightly scoring the column usually creates a cleaner opening.
