The entire EXP®2 Stem Trap and reusable holder are only slightly larger than a standard HPLC fitting. Its slim architecture allows it to easily fit into crowded instrument compartments or to connect directly to tightly-spaced injection ports. When tightened by hand, the EXP®2 Stem Trap seals to 8,700+ psi. All configurations incorporate wrench-flats to enable flawless sealing to 20,000+ psi (1,400+ bar).
The EXP 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. Specialized features, patented technology, precision engineering and state-of-the-art manufacturing make the new EXP®2 Stem Trap an unbeatable choice for ultra high-pressure nano-flow trapping applications.
The new EXP®2 design incorporates integral ferrule into the front-end of the holder. No separate ferrule to lose.
The unique packed floating stem installs directly into any 10-32 port and automatically adjusts to provide a perfect ZDV connection.
