ABSTRACT:
A sparging-infrared liquid analyzing system having a vessel in which a gas stream makes a single pass through a liquid stream containing contaminants, in order to provide vapor-to-liquid equilibrium of contaminants in the gas stream. The gas stream is then passed through a condenser, in which the gas temperature is precisely controlled, and the gas is cooled to a point below the dew point of water vapor in the gas stream. The gas is then flowed into a gas cell for infrared analysis. Water vapor effects are removed from the analytical output. Also, the effects of excessive depletion of relatively insoluble contaminants are removed from the analytical output.
