Total Flow

Hi camelia,

That is a puzzle. I cant think of anything except to examine both methods. Can you post the method parameters? Are both methods run on the same inlet and detector?

I updated the tags on the  post for better visibility.

Hi James

I have attached the 2 methods for you to examine. The methods are run consecutively using the same column, inlet and detector

Best Regards

Hi camelia,

I don't have a good explanation for this. Some things I notice that could play a factor. It looks like the DB1 specifications may have been entered manually?   This should still not make a difference. Have any of the columns been flow calibrated? Method 1 is isothermal while method two is a an oven ramped (temperature) method again, at start, shouldn't make a difference with constant pressure with the same start temperature. I welcome other community members input. The difference will not create a problem with method functionality.
