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 1075°C. 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 (1100°C), but wasn't
thrilled with the results. Interestingly, at 1250°C the results were worse.
Is life really that much better at 1400°C for glassy carbon?  Aside from
the Finnigan TCEA, what other high temp EA brands have folks had good
success with?

Thanks,
Toti
