Guard Column Kit, PEEK, 3.0 mm ID, 8 mm active length. ARE-Applied Research brand. 1 EA.
Additional Info:
The 49330‑GC1 All‑PEEK Guard Column Kit is designed for protecting analytical and semi‑analytical HPLC columns while maintaining a fully bioinert flow path. This complete kit includes the guard column holder and replaceable cartridge components, providing a convenient solution for extending column life in demanding applications.
Constructed entirely from PEEK (polyether ether ketone), including the frits, this system ensures a completely metal‑free environment, eliminating unwanted interactions between analytes and stainless steel surfaces. This is critical for proteins, peptides, nucleic acids, ions, and metal‑sensitive compounds, where adsorption or catalytic effects can impact recovery and data quality.
✅ Why Use a PEEK Guard Column Kit
Protects Analytical Columns Prevents particulates and contaminants from reaching the main column
True Bioinert Flow Path Eliminates metal interaction for sensitive analytes
Improves Column Lifetime Reduces fouling and extends column usability
Maintains Chromatographic Integrity Minimizes adsorption and preserves peak shape
Replaceable Cartridge Design Enables easy maintenance and cost control
Performance & Design
The guard column components are manufactured using a proprietary extrusion process that creates a smooth, mirror‑like internal surface, supporting:
Minimal band broadening
Low dispersion
Consistent flow characteristics
All wetted components—including tube and frits—are made from extruded PEEK, ensuring:
No chemical coatings or treatments
Uniform surface chemistry
Reliable bioinert performance
Carbon is incorporated into the formulation of the black components prior to extrusion, enhancing durability without altering surface chemistry.
