Easy to Use, Low Dead Volume—The Ultimate Combination of Convenience and
Column Protection
Unlike “one size fits all” guard systems, the Trident Direct system gives you the power
to select the right level of protection for your analysis. The system offers three levels of
protection and guard cartridges in four dimensions, with a variety of bonded phases to
match your analytical column. The economical, leak-free cartridge design provides an
unprecedented combination of convenience, economy, and reliability. The foundation
of the Trident Direct system is a reusable direct connect holder that easily attaches to
any HPLC column using CPI- or Waters-style end fittings.* The system is available in
configurations to match different protection level needs: in-line filter, in-line filter with
holder for 10mm guard cartridge, and in-line filter with holder for 20mm guard car-
tridge. The guard cartridges are available in 2.1 and 4.0mm ID and are interchangeable
within the appropriate length holder.
*The standard PEEK tip in Trident Direct systems is compatible with Parker, Upchurch Scientific, Valco, and
other CPI-style fittings. To use Trident Direct systems with Waters-style end fittings, replace the tip with

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

" 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 either 10mm or 20mm guard cartridges. Either
size can be purchased with or without a prefilter, which provides added protection
against the particles that can shorten the lifetime of the guard cartridge.
