Response difference between packed and unpacked liner

I am seeing a 10 fold increase in response when I use an unpacked single tapered liner instead of my usual glass wool packed single tapered liner (SGE Focus Liner). I expected to see some difference but not as much as this. Anyone got an explanation.
Cheers

Martin,
Would you add what the analyte is and its concentration.
Thanks.

I am using an in-house test mix containing compounds with a variety of functional groups at concentrations of approx. 0.1% in acetone. Injections are 100:1 split. All compounds are affected equally.

Hi Martin
Like a lot of people posting problems you are making this difficult by supplying information one little piece at a time as if you are a suspect being interrogated !!
Please supply FULL details of your set-up and methods, i.e. column dimensions, flow rates, injection manual or auto etc etc so that a diagnosis does not have to be based on guesswork.
Thanks Peter
