Abstract
Systems for a managing a chemical process and photoionization detectors for analyzing a process gas are presented. In one aspect, the system includes a process gas source in fluid communication with the process chamber and a photoionization detector. The photoionization detector is configured to analyze the process gas. The photoionization detector includes a heat resistant coupling for connection to the system, a gas sample chamber with the radiation window soldered or brazed to a wall of the gas sample chamber, and a radiation source configured to emit radiation through the radiation window and into the gas sample chamber to analyze the process gas. In another aspect, the photoionization detector includes a removable coupling, a gas sample chamber, and a radiation source. The removable coupling is for connection to the process gas handling system and includes a metal gasket and metal flanges.
