Hello, folks,
I run a Carlo Erba NA1500-Optima with both DI and continuous flow.
It was set up to run C and N isotopes only, and I am
attempting to obtain 34S from 66SO2. I have made all the
physical upgrades for this, and am running conflow, using the
DI ref system as my source of SO2 ref gas.
I have run samples against my ref gas(set at 0.00 per mille
for now) and have good traces, but the computer does not
calculate them. The print out for isotopic calculations reads
"no peak", and "0.00" for its calculation of delta and atom%
values. Also Std Dev of fit is "N/A".
I THINK it is a software problem. The software is EA 1.4.
Any words of advice from seasoned users?

Thanks,
Richard.
