This should take less than one hour. The ion source and quad(s) only need to be below 100° C and the high vacuum pumps - diffusion pump off and cold or the turbo pumps not spinning. Make sure that the GC transferline temperature is set to OFF or 0° C…
The GC inlet must have 20 ml/min or more total flow for good inlet pressure/flow control. If the total flow is too low, air can actually diffuse into the system and the oxygen will damage the column.
Using an Agilent Headspace Sampler the samples are…
Hello ljones031 ,
I would suggest copying the installation files to a folder on the local hard drive and then disconnecting any external drives before attempting installation. Most MassHunter programs will try to install to a D: drive it if is found…
Hello,
If you need the formatting of a table, it can be done that way. I do not like to use multiple hidden tables for that kind of report as they can be hard for later customization. The example below uses a single hidden table and custom code to…
Hello Agilent Users,
Im missing a feature in Openlab since day 1. How do I override and start a run if the GC is not ready ?
For example: the FID temperature is set at 250°C in the method and the actual temperature is at 220°C (it is still heating…
Hello Marty,
thanks for your reply. I tested your hint. It worked and I'm confident to code the formula in the CC.
Thank you very much and have a nice weekend,

Hello well ,
I know this is an old forum post, but just wanted to add to what ISH was saying.
The answer still stands, 6890 is not compatible with the 7650 ALS. The GC models it is compatible with are (at the time of this comment at least):
- 8890…
