Dear all:

I will appreciate it if anybody may provide some information about D/H
isotope analysis method for chlorinated volatile organic compounds. I tried
closed tube combustion at 525 degree C with the mixture of dichloroethane,
CuO and Ag. I got scattered delta-D values (+- 5). Are there any byproducts
between the combustion ingredients that may affect the D/H isotopes?

Thanks for help.
