I used to quantify acrylic acid with an FFAP column,but after 2/3 injections,the performance of the column is bad,tailing etc..
My parameters are on column inj. ffap 30*0.53*1.0
solvent Etoh oven programm70°C 1min-10°C/min-230°C
Does anybody know?

Polymerization of acrylic acid in the column at high temperature?

What temperature his high enough for polymerisation?

Acrylic acid, unless stabilized, will polymerize even at room temperature. At elevated temperatures the rate is much higher. You might want to try HPLC
