He damned sure doesn't like it when I nitpick.

Yeah, but Pot and Kettle are not terms either one of us should be tossing
around carelessly. We both bear more than a little physical resemblance.

Please don't. I considered doing it myself, but decided it was a lot
easier, and almost as safe, to accept your numbers as posted.

Foolish me.

Just because you have a dark tan and wear lots of heavy shiny jewelry
doesn't mean you look black, and I'm even whiter than you.

I don't know nuttin bout trimix, but five ten thousandths of a percent
doesn't sound like it could make any difference at all.

Seems like you'd need some expensive lab equipment to even detect such
an infinitesimal amount.

HINT -- Check the percentage of helium in air...

OK, I get it.
Whoosh - right over my head.

(reminds me of the quizzical look I got when I requested 21% Nitrox)

Several explanations:

1) My shop uses french fry grease for compressor oil. <<<food
grade>>>

2) Technically, EAN21 is enriched with *precisely* 0 (zero) oxygen.
I've verified this with a Simson-Lawrence EAN6200 Nukyuler Mass
Spectromulator. It confirms *exactly* 0 (zero) on the "Enrichment"
scale. It has been recently calibrated by Bruce Wienke at LANL and
certified to be RGBM compliant.

3) In your perspective (lawyer) you should be familiar with 0%
enrichment. Isn't that what plaintiffs get from a lawsuit after legal
fees and expenses are subtracted from the award?

4) The air has also been "enriched" by virtue of purification. At 70%
RH and 80F, air is only about 20.4% O2. After cleaning and drying, it's
up to 20.9%
(unfortunately the Simson Lawrence EAN6200 Mass Spectromulator has a
fixed wavelength spinicumatator, so it's an inaccurate POS (How much
accuracy can you expect from *anything* that uses the word "nukyuler"
?). It has been enriched with ~2.45% additional oxygen content.

5) EANx has evolved as standard notation for O2 fraction for any
nitrox, while slash notation is reserved for helium. "EANx" is a
concise, unambiguous expression meaning N2 = 100-x. eg 50/50 is heliox
, 21/35 is trimix and EAN50 is nitrox.

Uh huh.

But seriously, has anyone tried making pure EANx, like mixing pure O2 and
pure N2, without any of those pesky trace gases that likely cause cancer? I
would pay good money for that.

There's a shop in the Dallas area that uses DNx, which uses osmosis to
remove the N2. As a result, they can just dial up a mix. The N2 is
normally just vented to the atmosphere, but I suggested that they
bottle it and sell it to the road racers that like to use nitrogen in
their tires. The only problem with the system is that it requires
5000 psi to work properly.
