I am trying to run a packed column on a 7890 GC. As far as I know, the system is setup correctly in terms of hardware. I am pretty new with packed columns on an Agilent GC, so I am not sure where to even begin in terms of method settings.
I am looking for optimal method settings. I am running phenethyl alcohol as a standard with He as the carrier. What are typical flow rates and oven ramps?
Currently, I am only getting a solvent front (MeOH) that is about a minute long and no phenethyl alcohol peak. Below is my current method.
Thank you in advance for any advise!
Oven Temperature: Initial
120° C Rate 20°C/minute
200°C (hold 3 minutes)
H2 Fuel Flow
Makeup Flow: He
Suppleco 80/100 Mesh 2 m x 2 mm 5% FFAP or Equivalent
I have moved your post to an application area so that it has more exposure. Packed column applications are rare today, I am hoping you get a connection with a user with a similar application.
