OPTI-PAK® Trap Columns are no longer available for purchase.
This page is being maintained as a technical reference for customers with existing OPTI-PAK® products.
For a current low-volume trapping option, please see the EXP®2 Stem Trap (Nano Flow). The EXP®2 Stem Trap offers an auto-adjusting zero-dead-volume connection, low-volume packed stems, and pressure capability up to 20,000+ psi.
Because the specifications and available configurations differ from the discontinued OPTI-PAK® Trap Columns, please review the EXP®2 product specifications or contact Optimize Technologies if you need help selecting the appropriate configuration for an existing application.
Legacy Product: 10-32 PEEK Holders and Custom Packed Cartridges
The following product information is retained for customers who currently use or need to identify legacy OPTI-PAK® Trap Columns.
OPTI-PAK® Trap Columns used a hardware design that integrated a PEEK holder with an auto-adjusting stem. This combination provided a fluid interface with any 10-32 standard injector port and a zero-dead-volume connection regardless of variance in tube stop depth. A proprietary method of frit placement allowed the packed stem to be positioned directly into the flow path, minimizing excess swept volume.
The low swept volume helped minimize sample dilution and dispersion.
OPTI-PAK® Trap Columns were designed for trapping, desalting, and pre-concentration applications. Trap columns could be installed into the outlet of a switching valve. A second trap could also be added downstream in the loop of an injection valve for comprehensive two-dimensional separation applications.
OPTI-PAK® Trap Columns were offered in capacities of 0.5µg, 1µg, 2µg, 4µg, 8µg, and 20µg, with bed volumes ranging from 0.12µL to 5µL. Packing material options included C18, C18AQ, C8, C4, SCX, SAX, DVB, and custom materials.
