OPTI-TRAP™ is a bi-directional trap cartridge system for sample concentration and purification. Cartridges can be used individually or in series.
The OPTI-TRAP system is rated hand-tight for use up to 1,500 psi (100 bar) and features low back pressure. Samples may be loaded and eluted manually with a syringe or used on-line when the system is plumbed into the sample injection valve. The bi-directional cartridge design supports flushing and bed regeneration. Transparent cartridge construction allows visual inspection of the packed bed, and color-coded bands identify packing material.
OPTI-TRAP cartridges/inserts are PCTFE with titanium frits for chemical compatibility and full biocompatibility.
Custom packing is available upon request.
OPTI-TRAP uses three cartridge size identities:
| Cartridge size | Bed volume | Dimensions |
|---|---|---|
| Capillary | 0.5 µL | 0.5 × 2 mm |
| Micro | 5 µL | 1 × 8 mm |
| Macro | 50 µL | 3 × 8 mm |
OPTI-TRAP phase identities are:
Choose a phase based on its suitability for your application, not availability alone. For exact chemistry identities and distinctions between related names, use the Trap Chemistry Reference.
Pack-size options are:

If you need help deciding whether OPTI-TRAP is the right trapping family, see the OPTI-TRAP family overview or the Trap Columns Hub.
For general trapping principles and terminology, use Trapping Fundamentals / Technical Reference. For chemistry interpretation, use the Trap Chemistry Reference.
The OPTI-TRAP system uses a biocompatible trap-holder assembly made of PEEK for the Capillary configuration and stainless steel with a PEEK flow path for the Micro and Macro configurations.
