Trident LC Column Protection System

Redesigned to be more rugged and easier to use!

  • Match your needs with three levels of protection: filter only, cartridge only, or filter and cartridge.

  • 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 replacement.
  • Direct connection eliminates tubing and connectors that increase system volume and leak potential.
  • Low-dead-volume design has negligible effect on chromatography.

Trident HPLC In-Line Guard Cartridge Holders

A Trident in-line guard cartridge holder can be used with almost any HPLC column by connecting it with a short piece of 1/16" tubing, appropriate nuts and ferrules, or finger-tight fittings. The system can be used with Restek columns, or with columns from other manufacturers. Holders are available for 10 mm guard cartridges. Purchase with or without a prefilter, which provides added protection against the particles that can shorten the lifetime of the guard cartridge.

High-Pressure Frit-Type In-Line Filter

Restek’s high-pressure in-line filter is a stand-alone version of the Trident column protection system, specifically designed for ease of use, low dead-volume, and flexibility. The filter has a replaceable, PEEK encapsulated 316 stainless steel frit with a surface area of 12 mm2. The standard frit with 2.0 µm porosity may be replaced with an optional 0.5 µm porosity frit. Use of this filter can greatly extend column life, thereby reducing costs and saving maintenance time. Tubing 1/16" OD; connectorsCPI.

Replacement Cap Frit Filters for Trident Guard Cartridges

Replacement guard cartridges can cost as much as an analytical column, so why not protect them, too? The removable cap frit filter in a Trident direct helps prevent clogged cartridges to extend the life of your column, your cartridge, and your budget.

  • Use 2 mm cap frit filters with 1.0–2.1 mm ID analytical columns.
  • Use 4 mm cap frit filters with 3.0–4.6 mm ID analytical columns.
