CO2 Gas Concentration Defined |

+

When measuring gases like carbon dioxide, oxygen, or methane, the term concentration is used to describe the amount of gas by volume in the air. The 2 most common units of measurement are partspermillion, and percent concentration. Partspermillion (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO2 means that if you could count a million gas molecules, 1,000 ...

PPM (Parts per million) is a measurement used today by many customers to measure quality performance. Definition: One PPM means one (defect or event) in a million or 1/1,000,000. There was a time when you were considered a pretty good supplier when your defect rate was less than 1%, (10,000 PPM), then the expectation was increased to % or 1,000 PPM. Now the rate for most automotive ...

20110405· If ppm is expressed as THE VOLUME of particles to a unit volume of water, then ppm BY VOLUME is equal to µl/l. However, if ppm is expressed as THE MASS of particles in a unit volume of water, then ppm BY MASS is equal to mg/l. To convert from ppm by volume to ppm by mass, multiply by the density of the particles. For mineral grains (clay, silt and sand sizes), this will typically be g ...
