Sažetak
The problem of »repeated peaks« associted with the direct gas chromatographic determinations of aqueous acrylic acid solutions with the concentration range of 0.05 – 10.00 g dm–3 has been discussed for the case of polyethylene glycol adipate as a stationary phase. Based on more than 700 injections of standard solutions on the packed column, a set of correction factors has been proposed. Simple relations between the »repeated peaks« heights and the reference solution concentrations were found. The reproducibility of the method was evaluated.
