The MSD transfer line is the heated connection that carries analytes from the GC column into the mass spectrometer. In this video, I show how I replace the transfer line on an Agilent MSD. I cover: • Accessing the transfer line assembly • Disconnecting the existing transfer line • Removing the old transfer line • Installing and positioning the replacement • Reconnecting the assembly • Checking the final installation before returning the MSD to service The transfer line does n

A GC/MS acquisition method is much more than an oven temperature program. In this video, I walk through the GC-side parameters I review when setting up an Agilent GC/MS method and explain what the major settings control. I cover: • Injection volume and syringe parameters • Pre- and post-injection solvent washes • Sample pumps and vial mixing • Split/splitless inlet temperature • Inlet pressure and flow settings • Pulsed splitless parameters • Purge flow to the split vent • Co

After cleaning a GC/MS ion source, the next step is reinstalling it correctly and returning the MSD to vacuum. In this video, I show how I reinstall the cleaned ion source in an Agilent GC/MS and initiate the pump-down process. I cover: • Positioning the cleaned ion source • Reconnecting the source components • Checking that the source is seated correctly • Closing the analyzer • Starting the pump-down cycle • Monitoring the vacuum system as the MSD returns toward operating c

Before cleaning or servicing a GC/MS ion source, the source first has to be removed correctly. In this video, I show how I remove the ion source from an Agilent GC/MS for maintenance. I cover: • Accessing the analyzer after the MSD has been vented • Opening the analyzer • Disconnecting the source assembly • Removing the ion source • Handling the source carefully before cleaning or service Ion source removal is a routine part of GC/MS maintenance, but the sequence matters. Und

Before cleaning a GC/MS ion source, it has to be disassembled carefully and kept organized. In this video, I show how I disassemble an Agilent EI extractor source before cleaning. I cover: • Removing the source components step by step • Disconnecting the filament and electrical connections • Separating the source body and lens components • Removing the smaller screws and source parts • Handling the components with clean gloves • Keeping everything organized for cleaning and r

Clipping a GC column can shift retention times — but your GC/MS calculation method still contains the old values. In this video, I show how I update retention times in Agilent EnviroQuant after trimming a GC/MS capillary column. I walk through the actual software workflow: • Review the chromatogram after the column has been clipped • Check the new compound retention times • Load the appropriate quantitation/calculation method • Confirm compound identification • Open the calib

How to replace a capillary GC column in an Agilent GC/MS. In this hands-on video, I walk through capillary column installation from the inlet to the MSD transfer line. Topics covered: • Preparing the column for installation • Making a clean, square column cut • Installing the correct nut and ferrule • Setting the correct column insertion depth at the inlet • Installing the column into the MSD transfer line • Avoiding leaks and poor positioning • Checking the installation befo
