When replacing the PFTBA solution in the calibration vial, the manual says to turn the analyzer off? Does anyone know exactly what this means? Do I need to vent and turn the power off?

Hi Lee-Anne let us know if the information (Step 2 and Figure 1 Video) contained in this article helps: Refilling the EI Calibration Vial for the Agilent 5975 and 5977 Series GC/MSD

Thanks for your reply Kristen, the article just says tune the MS off, I would like to know if you need to vent? I do not use Mass Hunter, I use Open Lab CDS.
Hi Lee-Anne,
Without vent how you will remove calibration vial to fill PFTBA.
First, vent the system and then better switch off System and then remove air by opening knob near vial.
Fill PFTBA carefully, not to damage o-ring.
If doubt then better call to your local agilent support to do onsite..
Hi ISH, Thanks, I just thought there might be an isolation valve to allow topping up without venting. Thanks, for clarifying.
If the valve is closed why do you need to vent it? Why don't I see PFTBA in every sample then. Instructions don't say to vent it.
Hi all, garyb007 is correct. As long as you are not scanning with the MSD, you can replace PFTBA and then follow the procedure to purge the cal valve.
