Dear XAFS community,
We've been developing air-sensitive sample cells for several of our XAFS
experiments, but we don't have a good way of characterizing how well they
actually reject air and water. Does anyone have recommendations for easily
available 3d transition metal compounds that have a
Fe2+ is notoriously sensitive. I think TiCl4 (a liquid) is used to test dryboxes because it hydrolyzes easily with production of white smoke if exposed to water vapor. If a small amount of this were mixed into a degassed binder, its XANES would

Hi Jerry,
It's not a metal compound, but methyl viologen has always been my go-to for
anaerobic validation and has worked well for sample cells and glovebags and
such.

Hi Jerry,
I've seen people use various Li ion battery materials, lithium is nice, but
doesn't work here. Maybe NMC811 would work, it is unstable to exposure to
air and moisture. You could try some iron powder from a hand warmer pouch,
it will oxidize from ambient oxygen.
