Unlike "one size fits all" guard systems, the Trident LC column protection system gives you the power to select just the right level of protection for your work. With three levels of protection and a variety of guard cartridges and cap frits, you can select the best combination to match your specific analytical needs. Choose a filter alone to remove particulate matter, a guard cartridge alone to remove irreversibly adsorbed compounds, or both a filter and a guard cartridge for maximum protection. The economical, leak-free design provides a highly versatile combination of convenience, economy, and reliability.

The foundation of the Trident LC column protection system is a reusable, direct connect holder that easily attaches to any HPLC column with standard 10-32 thread ports.* The holder’s durable metal tip and replaceable PEEK ferrule allow a leak-tight seal onto the column to be made quickly and easily without tools. Guard cartridges are available in both 2.1 and 4.0 mm IDs, and the redesigned holder houses either size securely. Because the holder components are machined from specialized materials that will not gall or bind, an optimal seal is created that will withstand rigorous repeated use when installed according to instructions. The holder has also been designed for easy removal of the cap frit, allowing you to replace the cap frit filter in just seconds.

Finally, since the Trident LC column protection system is engineered to be exceptionally low dead volume; it has minimal effect on retention, peak shape, and efficiency. Protect your analytical column and preserve method chromatography with a Trident LC column protection system.

* Fittings on all LC columns have 10-32 threads; however, seat depth varies. An improper seat will yield a poor connection and may affect chromatography. While all Restek LC columns will provide a zero-dead-volume connection when used with a properly installed Trident LC column protection system, analysts should consult the manufacturer for non-Restek column connections.

特点与优势

Superior Protection in an Easy-to-Install Design.

• Match your needs with three levels of protection: filter only, cartridge only, or filter and cartridge.
• Durable metal tip with replaceable PEEK ferrule means easy installation onto column without tools.
• Improved thread design and materials create an optimal seal that releases and reseals easily, allowing multiple installations without galling and binding.
• Easy-to-remove cap frit simplifies filter and cartridge replacement.
• Direct connection eliminates tubing and connectors that increase system volume and leak potential.
• Low-dead-volume design has negligible effect on chromatography.
