Abstract
A system includes a moisture analyzer configured to detect moisture in a process gas. The moisture analyzer includes an absorption cell that encloses and conducts the process gas. The moisture analyzer also includes a pressure control device that may reduce a pressure of the process gas inside the absorption cell. The moisture analyzer includes a light emitting device that may transmit light through the process gas inside the absorption cell, as well as a photodetector that may detect an intensity of the light transmitted through the process gas and exiting the absorption cell.
