Correct column installation at the detector is just as important as installation at the GC inlet. In this video, I show how I install a capillary GC column into an Agilent micro-ECD (µECD). I cover: • Preparing and trimming the capillary column • Installing the ferrule and detector fitting • Measuring the correct insertion depth • Positioning the column in the micro-ECD • Tightening the detector connection • Checking the final installation Incorrect detector-side column posit

One GC inlet can be configured for two capillary columns. In this video, I show how I convert a single-column installation to a two-column installation in the same GC inlet. I walk through: • Removing the existing single-column connection • Preparing both capillary columns • Using a dual-column inlet adapter • Installing a two-hole Vespel/graphite ferrule • Measuring the correct insertion depth • Positioning both columns in the inlet • Tightening the connection • Checking the
