Air Quality checking equipment.

[Rmachandran]

Dear Sirs. in a book Samuel S.Butcher, Introduction to Air Chemistry, Academic Press, Newyork 1972 , he quotes about the chemical content of a room as Content of the air in dry atmosphere
N2 Nitrogen 0.78
O2 Oxygen 0.21±6X10-5
40AR Argon 9.34X10-3
CO2 Carbondioxide 32.5X10-4
NE Near 1.818X10-5
HE Helium 5.24X10-6
CH4 Methane 1.2-2.0X10-6
KR Krypton 1.14X10-6
H2 Hydrogen 5X10-7
XE Xeno 8.7X10-8
CO Carbon Monooxide 8*10-8-5X10-7
N2O Nitrous oxide 2-4X10-7
SO2 Sulphur dioxide 7X10-9
NO nitric oxide 10-8-10-6
NO2 Nitogen Di Oxide 10-8-10-6
HCHO Formaldelyde 10-7-10-6
NH3 Ammonia 10-6
O3 Ozone 0-5X10-8

I wish to know more about the equipment/ apparatus he used to measure the contents in the room.

That would be a good letter to send to the publisher rather than posting to random forums in their Astronomy section.

Especially since it has nothing to do with astronomy.

Rmachandran;

A mass spectrometer, perhaps? Maybe a variation on gas chromatography for the volatiles?

Just trying to be helpful. But, this really isn't the kind of question for "Ask the Astronomer" forum. "Physics" would be more appropriate.

Good suggestion for the forum...

Perhaps the poster should read the book?

Maybe he's just got a really sensitive nose :?:

Off planet habitats, and spacecraft will have similar concentration of these and other gases and vapors, so the question applies to some of the space.com forums. Perhaps the people at your local EPA office can tell you how they measure the levels in your community. Neil
