I am using a SEC column (mAb PAC SEc-1 from ThermoFisher) to analyse an IgG sample but I am always having problems with the first injection from each vial: The peaks have lower intensity than the ones for the following injections.
Has anybody had the same problem?
My system is an Agilent 1260.
Thanks in advance.
