Gases that make up outdoor air: this article provides a table of the components in outdoor air - a list of the various gases found in air by percentage.
The table gives the percent of each gas found in typical outdoor air, includes citations of authoritative sources, and discusses variations in the data. These gas percentages are a useful reference for comparison when making both outdoor and indoor site measurements and studies of air quality and air contaminants.

Outdoor air is commonly used as a baseline for comparison with indoor air quality. Provided that the outdoor air location sampled is not close to a particular source of contamination such as particulates or chemicals from a nearby trash burning or industrial facility, or such as gases from an adjacent garage or highway this is a reasonable approach. The table below provides the components of indoor air in typical percentages of make-up.

Technical Reviewers & References
The first detector tube was used in the U.S. in 1919 (for CO). Modern tubes offer quantitative results with a high degree of accuracy and selectivity. Basically, a "tube" is a glass tube which contains one or more chemical reagents which react with the measured substance by changing color, hence the name "colorimetric gas detector tubes".
In most tubes, the length of stain, combined with the volume of pumped test-air and with other environmental variables such as RH and temperature provide a quantitative measure of the level of target substance present at the instant of sample collection. Other methods are available for long-term sampling where that approach is needed.
Draeger Simultaneous Sets I and II measure inorganic combustion gases. Set III is for the measurement of organic vapors, most of which are not pertinent to this fire. The specific substances tested and the test results for each are listed in our Lab Report.
 Draeger Sampling Pump: I use the Draeger accuro 100 ml multi-stroke bellows Pump and Draeger-Tubes for gaseous substance sampling, or the Sensidyne Gastec 100 ml multi-stroke piston pump and Gastec tubes for certain gaseous substances. Both pumps are factory calibrated at 100 cc, and are leak-tested before and after each investigation. The adsorption tubes used for substance screening/identification are factory-calibrated.
