Full-Evaporation Head-Space Gas Chromatographic Technique for the Determination of Residual Monomers and Volatile Organic Compounds in Polymer Dispersions.

Full-evaporation head-space gas chromatography is a useful technique for the determination of free monomers and other volatile molecules contained in polymer dispersions. The method has a large working range and good repeatability. The absence of contamination in the syringe and the injection line makes it applicable in gas chromatographs equipped with autosamplers. A detailed description of the method and a comparison with the "traditional" head-space gas chromatographic technique and the liquid-injection technique described in ASTM D 4827-93 are presented.
