A convenient and quick method has been developed for simultaneous detection of several low molecular weight chlorinated organic compounds (LMWC) in polyamideamine-epichlorohydrin (PAE) solution, using headspace-solid phase microextraction-gas chromatography (HS-SPME-GC). The method consists of extracting a sample containing 0.42 g/mL NaCl with an 85 µm polyacrylate (PA) coated fiber at an extraction temperature of45    ∘    C   {45^{\circ }}\text{C}   , for an extraction time of 30 mins, and desorbing the analytes at240    ∘    C   {240^{\circ }}\text{C}    for 6 mins. Under these optimized conditions, relatively low limits of detection (LOD) of the analytes, good linearity (r    2    ≥  0.9934   {r^{2}}\ge 0.9934   ) and precision (relative standard deviation (RSD  ≤  4.38    %   \text{RSD}\le 4.38\hspace{0.1667em}\%    )) were obtained. Taking into account the matrix effect, standard addition methodology was applied to validate this method and recovery values were between 91.59 % and 109.69 %. This method is therefore well-suited for accurate determination of low levels of LMWC in PAE.
