Folks,

I'm shopping for a new EA to lighten the work load of my current one (Euro
EA) that we use for typical EA stuff: basically CN isotopes and ratios in
organics. We also run a lot of waters using chrome reduction at 1075C. I'm
considering a high temp that will be used solely for glassy carbon
reduction in solid samples and chrome HD for water.

Question:
I've run oxygen using glassy carbon at lower temps (1100C), but wasn't
thrilled with the results. Interestingly, at 1250C the results were worse.
Is life really that much better at 1400C for glassy carbon?  Aside from
the Finnigan TCEA, what other high temp EA brands have folks had good
success with?

Thanks,
Toti
