Ordinarily, the analysis is applied in the field using the portable, orsat apparatus to determine the volume composition of carbon monoxide, carbon dioxide, oxygen, and unsaturated hydrocarbons in the gaseous emission from combustion processes. Results are usually expressed in volume percent of each component gas.
Use of Orsat The levelling bottle, tubing and gas burette are filled with acidulated water and connected to the gas flue via the aspirator. Flue gas is then pumped through these parts (escaping through the levelling bottle, held low) until the gas in the burette is representative of the flue gas.
An Orsat gas analyser or Orsat apparatus is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content.
ˈȯrsət-, -ˌsat- : an apparatus for gas analysis that consists essentially of a measuring burette, a connected series of pipettes containing selective absorbents, and usually a combustion pipette.
The Orsat apparatus allows for the analysis of flue gases by passing them through three absorption bulbs containing different solutions. The first bulb contains potassium hydroxide and absorbs carbon dioxide. The second bulb contains alkaline pyrogallic acid and absorbs any remaining carbon dioxide and oxygen.
