Dear list members,

I would like to set up a system for collecting precipation for isotope
analysis.  What I have in mind is a setup that could be left unattended for
up to 2 weeks without samples being comprimised.  I would appreciate any
thoughts or ideas concerning this issue such as designs or companies that
may sell the proper equipment.

Thank you,

Hal Karlsson
