The makeup gas adapter is part of the gas-flow path for an Agilent micro-ECD. In this video, I show how I install the makeup gas adapter on the micro-ECD assembly. I cover: • Accessing the micro-ECD • Removing the existing fitting • Preparing the replacement adapter • Installing and positioning the adapter • Tightening the connection • Checking the completed installation It is a small component, but correct installation is important for maintaining the detector gas-flow path
