How to configure Agilent GC software for two columns sharing one inlet, with each column connected to a different detector. This tutorial demonstrates the software configuration using two Agilent software platforms: First half – MassHunter How to configure a dual-column, dual-detector setup in Agilent MassHunter software. Second half – ChemStation How to configure the same arrangement using Agilent ChemStation software. The configuration includes: - One injection inlet - Two

Step-by-step replacement of the heater and temperature sensor assembly in an Agilent Micro-ECD (Micro Electron Capture Detector). In this 11-minute hands-on tutorial, I demonstrate how to access the detector components, remove the existing heater and sensor assembly, and install the replacement parts. The heater and temperature sensor are essential for maintaining stable detector temperature and reliable gas chromatography performance. Topics covered: - Accessing the Micro-EC

How to replace the gold seal on an Agilent 7890 GC inlet. This video shows the hands-on process of removing the lower inlet hardware, replacing the gold seal, reassembling the inlet, and reinstalling the GC column. For trace-level GC/MS analysis, inlet contamination and active surfaces can contribute to poor response, peak tailing, discrimination, elevated background, and failing CCVs. Gold seal replacement is an important part of maintaining a clean and inert GC inlet flow p
