Balston FT-IR Purge Gas Generator

Balston FT-IR Purge Gas GeneratorThe purpose of providing a dry CO2-free purge to an FTIR spectrometer is twofold. The purge prevents deterioration of the beamsplitter by moisture and also eliminates undesired absorbance by water and carbon dioxide in the background. Consequently, the purge enhances the instrument’s reliability by the reduction of the potential need for service and increases the accuracy of analysis and signal to noise ratio through the elimination of inconsistencies in the background levels of water and carbon dioxide. A Parker Balston FTIR Purge Gas Generator is specifically designed to provide a purified purge and air bearing gas from compressed air. The FTIR Purge Gas Generator supplies the carbon dioxide-free air at less than -100° F/-73° C dew point with no suspended impurities larger than 0.01 micron. The Parker Balston Purge Gas Generator completely eliminates the inconvenience and high costs of nitrogen cylinders, dewars, and significantly reduces the costs of operating FTIR instrumentation.
