Not that I know anything about it (I don't), but given
that feirceness' theory is correct, you would'nt want anything to condense untill it had gotten into the place
you'd want to collect from. no?
This could be a thing where a coldfinger would be used,
a large surface area coldfinger. It's not resubliming going
on but it seems similar in that a bond is formed
then broken, within a wide temperture range.
If it solidfied on the "coldfinger" it would seem that
it'd have to be scraped clean then put back in.
This is just a theory
