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.

• Use with almost any HPLC column
• For 10 mm guard cartridges
• Available with or without filter

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.
