Dear Scott, We have done some time-resolved XAFS measurements on aqueous solution of Ru(II)(bpy)3 complex using free-flowing jet. It forms a liquid sheet of approx. 100 microns thickness and thus you can avoid windows etc. However you might run into some trouble when using in vacuum. In principle you can find many manufacturers who provide these kinds of jets equipped with sapphire nozzles for dye lasers. I know that some of these jets are also used for cutting and polishing jewelry...if you need any more details you could look up our paper about the setup: M. Saes et al., Rev. Sci. Instrum., 75(2004), 24-30.

Hi all,

I've been doing a literature search for an article I'm writing up, and I can't seem to find any examples of an XAS flow cell desgined for liquids. Sealed cells for liquids, yes; flow cells for passing gases over solids, yes; but no solution-chemistry flow cell.

Simon Bare uses a flow cell for passing liquids/gasses over a sample. This one is a glass container with kapton windows with ports for input and output. Also I have seen something like that at PNC cat. I think that Ed Stern et. al. was using it. The one at PNC cat circulated the liquid through a boron carbide section that is x-ray transparent.

We (Penner-Hahn group) have done solution EXAFS measurement and time-resolved XAS at Bio-CAT at the APS. A Kapton tube is used for x-ray window and connected to PE tubes using epoxy glue.

Maybe not exactly a flow cell, but a rapid biblio research on "Web of Science" using the"stopped-flow" and "EXAFS or XAS or XANES" keywords has unearthed some 23 references over the last ten years, many of them probably utterly irrelevant. Nevertheless, I copied them in the attached text file. Best regards, Michel Schlegel
