WHAT IS MEANT BY A CONDITIONING SYSTEM?
Extractive type analyzers draw a small sample of the stack gas, which is then introduced to the analyzer. Extracted stack gas contains a large amount of water vapor and, in the case of liquid and solid fuels, it also contains soot particles. Soot particles are removed by means of porous or fiber filters that are designed not to remove any of the desired gases. In portable analyzers water vapor is removed either by condensing it or by using a permeation type drier. Condensation can be accomplished either by a simple catch pot or by cooling the sample using a chiller. The combination of filters and water removal system is called the analyzer’s conditioning system.
