	A couple of days ago I received an E-mail message from Peter Fritz
concerning chlorine and carbon isotope measurements on chlorinated solvents
and organic compounds.  This message is to inform you that I recently
conducted a study on five chlorinated solvents (PERC) purchased from local
dry cleaners.  We measured delta 13C on CO2 after closed tube combustion on
an IRMS and delta 36Cl on AgCl from PARR bomb combustion at Lawrence
Livermore National Laboratory on an AMS.

	If you would like more information, I will be pleased to speak to you or
correspond with you.
