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,

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.

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 'reasonable' amount of air sensitivity for purposes of sample call validation?  Any suggestions for other methods to validate performance? We would grind the sample and form a pellet with a degassed binder, in a glovebox or glovebag.
With thanks,
Jerry
