Edit the ALS injection style in the method from ALS to manual. Start the run in the software. Press the start button on the front of the GC.
Another option is to take the syringe out of the ALS, and run with your existing configuration and method.
Configure a non-existent gas sampling valve on the GC. It does not need to physically exist to configure it. Do NOT add a multiposition valve unless you actually have one. Select that gas sampling valve as the injection source for the run.
What context is this for? We have done something similar to see if there were contaminants inside the GC or not. To test it we did two things, one, same as trifecta, and injecting from a empty vial.
I will mark as assumed answered due the age of this post and suggestions from other community members. Feel free to post again if you are looking for more suggestions.
The best way to do this is:
1. Edit GC method, click Configuration and make sure that a Gas Sampling Valve is configured. You don't actually need a real valve, just add one to the method.
2. Edit the injection style to Valve/Immediate Start instead of ALS.
Save method and run it, you'll find that it starts a run without using the autosampler.
