Specifications:

Wooden/Laminated Cabinet with front and rear sliding doors

having provision for hanging absortions pipettes with three adjustable compartments and gas burette, manifold three way and cylinder

with three absorption pipettes of two compartment type, 100 ml Gas Burette with outer jacket, manifold with stopcocks, and aspirator bottle, for the analysis of CO, O2, CO2 particularly in fuel and furnace gases,

PROCEDURE:

The apparatus consists essentially of a calibrated water-jacketed gasÊburetteÊconnected by glassÊcapillary 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.

By means of aÊrubber tubing arrangement, the gas to be analyzed is drawn into the burette and flushed through several times. Typically, 100ml is withdrawn for ease of calculation. Using the stopcocks that isolate the absorption burettes, the level .

The gas is then passed into the caustic potash burette, left to stand for about two minutes and then withdrawn, isolating the remaining gas via the stopcock arrangements. The process is repeated to ensure full absorption. After leveling the liquid in the bottle and burette, the remaining volume of gas is assumed to be nitrogen and indicates the percentage of carbon dioxide absorbed.

Usage: AnÊOrsatÊgas analyser is a piece of laboratoryÊequipmentÊused to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, theÊOrsatÊremains a reliable method of measurement and is relatively simple toÊuse
