The patented hand-Tight EXP® trap column is rated for use at 20000+ psi (1400+ bar). This unique design connects directly to any injection valve (with 10-32 threads) or in-line with ¹/₁₆" stainless tubing for unparalleled convenience and efficiency.

• Rated to 20000+ psi (1400+ bar)
• Bed volumes from 1.6 to 600 μl
• Convenient means of handling a variety of sample clean-up and enrichment processes
• More efficient than off-line trapping techniques
• Hand-tight trap replacement - no tools required

The EXP® cartridge system enables chemists to quickly remove detergents or salts which can affect the ionization process in MS work. This trapping technique can concentrate the sample directly on-line, allowing for increased recovery of precious sample material compared to off-line techniques. On-line trapping readily lends itself to automation for high-throughput analysis in UHPLC/MS applications. Free-Turn® architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/outlet.
