I was using a FFAP column to determine acetic acid in water .My brand new Nukol begins to tail terrible the acetic acid after only 140 injections.
is the lifetime for FFAP column so short?

What's your program temperature for your application ? What's your dilution solvent ?
You can try working at lower temperature (beyond 250°) or buy a column with a bigger film thickness, it will result in a longer lifetime.
