XL Column Repacking Service

Choose XtendedLife Hardware at Initial Purchase

• High-quality media yields excellent lot-to-lot performance.
• Compatible with SFC upon request.
• Available in dimensions up to 50mm i.d.

When column performance is past optimal, use the XL repack service:

Stationary Phase Details

• Successful retention and separation of moderately hydrophobic analytes.
• Best for fatty acids, which are too hydrophobic for analysis using C18 columns.
• C8 (USP L7) selectivity.

Faster Separations

• Higher analytical throughput compared to C18 alkyl chain chemistry.
• Faster compound elution due to reduced hydrophobic interactions.
