Constant column + makeup flow

Hi,

I am using a 6890 GC in split mode with an isothermal temperature and no flow ramp and operating in constant pressure mode.

Please can you advise how using the setting constant makeup flow for the FID detector is different to constant column and makeup? Under the method conditions stated will the flows be the same if either setting is used?

Thanks
