Your GC/MS calculation method controls how compounds are identified, quantified, calibrated, and evaluated. In this video, I walk through the key calculation-method parameters in Agilent EnviroQuant and show what I review when setting up or checking a method. I cover: • Compound identification settings • Internal standard assignments • Quantitation and qualifier ions • Retention-time parameters • Calibration levels and concentrations • Calibration curve and response-factor se

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

Pumping an Agilent 5977 GC/MS back down after maintenance is the moment you find out whether everything was put back together correctly. In this video, I show the pump-down process after the MS has been opened for maintenance. I go through: • Closing the analyzer and establishing the initial vacuum • Starting Pump Down in Vacuum Control • Watching the foreline pressure decrease • Monitoring the diffusion pump, source and quadrupole status • Confirming the system reaches READY

How to properly vent an Agilent 5977B GC/MS before performing mass spectrometer maintenance. In this hands-on video, I demonstrate the venting process and show what happens as the MSD prepares to come out of vacuum. Topics covered: • Preparing the GC/MS for venting • Opening Vacuum Control • Starting the vent cycle • Cooling the ion source and quadrupole • Monitoring temperatures during shutdown • Allowing the high-vacuum system to shut down correctly • Knowing when the MSD i
