pulse-dampened pumping system for post column derivatization

I'm looking for a pulse-dampened pumping system for post column reagent delivery. Then found the one as below :

Any good experience with this one? There is not too many information on the website.

Thank you.

This is actually an OEM from LabAlliance/SSI http://www.laballiance.com. It should work. The pulse damper requires back-pressure of ~1000psi in order to work correctly. Use a restrictor loop or a packed tube rather than a back-pressure regulator. You can also check Pickering Laboratories http://www.pickeringlabs.com if you want a deluxe system.
