Hello, Mike:

The cs would not have to evaporated. An ultracentrifuge
could spin it down before putting it in the x-ray beam.
Gelatin capsules or gelatin tubes are usually used as the
amorphous container for such a wet sample.

My usage of the word oligodynamism adheres to its
original, etymological and still-current meaning denoting the
phenomenon of dilution increasing potency, especially
in disinfection. It's an amazing phenomenon (but not
magic ;-)

Best regards,

Matthew
