RIVEROS, Héctor G.; OVALLE-MARROQUIN, Pilar  y  LARA, Armando. Oxygen Measurement in Gas Mixtures. Rev. Soc. Quím. Méx [online]. 2000, vol.44, n.2, pp.101-103. ISSN 0583-7693.

The measurement of oxygen y gaseous mixtures has many applications, and then a variety of sensors have been developed. Also, many books for children say wrongly, that they "measure" the oxygen in the air with a lit candle. We use the slow oxidation of iron, to absorb the oxygen in the air, and use the change in gas volume to measure its concentration, avoiding problems related to the combustion products and the heat released in the reaction.

Palabras llave : Oxygen; gas mixtures; oxidation; absorbtion; concentration; combustion products.
