EXP® In-Line Holder

Part Number:

Sorry but this item is currently unavailable.



The EXP® In-Line Holder is rated to 20,000 psi with hand-tight replaceable cartridges. This unique design connects in-line to any UHPLC system or injection valve with 1/16” stainless tubing and included EXP® fittings.  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.
