RE: EC sources

["Jean-Francois, Stephane" <stephane_jeanfrancois@merck.com>]

I tend to agree with the previous message. Once in a while, I found the
exhaust end of the EC detection unit contaminated with tritium. So it is
very iomportant ito vent the system in a fume hood (don't laugh, I saw
places where the "leaking " detector was vented in the room....

I'm surprise to still ear about this units (made by Outokumpu if I recall
well.) I was under the impression that they were replaced by Ni-63
trouble-free ECD units !
