  • Method for the determination of organic acids in an aqueous sample by; gas chromatography
    Patent number: 4960444
    Abstract: A gas chromatography method for the determination of organic acids using an otherwise conventional gas chromatography system, the advance being injecting a predetermined volume of an aqueous sample containing the organic acids for separation in a gas chromatography column having a polycarbonate resin stationary phase. The use of the polycarbonate resin stationary phase results in a method more resistant to the development of tailing peaks and other problems than the use of prior stationary phases. The method is especially beneficial for determining acrylic acid monomer in mixtures of acrylamide monomer and water.
