INTRODUCTION :
An Orsat gas analyzer is a piece of laboratory equipment used to analyze a gas sample (typically fossil fuel flue gas) for its oxygen , carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to use.
CONSTRUCTION:
The apparatus consists essentially of a calibrated water-jacketed gas burette connected by glass capillary tubing to two or three absorption pipettes containing chemical solutions that absorb the gasses it is required to measure. For safety and portability, the apparatus is usually encased in a wooden box.

THE ABSORBENTS ARE:

• Potassium Hydroxide (Caustic Potash)
• Alkaline pyrogallol
• ammoniacal Cuprous chloride
• The base of the gas burette is connected to a leveling bottle to enable readings to be taken at constant pressure and to transfer the gas to and from the absorption media.
• The burette contains slightly acidulated water with a trace of chemical indicator (typically methyl orange) for coloration
