Simple and accurate method for determining dissolved inorganic carbon in environmental water by reaction headspace gas chromatography

Abstract: We investigate a simple and accurate method for quantitatively analyzing dissolved inorganic carbon in environmental water by reaction headspace gas chromatography. The neutralization reaction between the inorganic carbon species (i.e. bicarbonate ions and carbonate ions) in environmental water and hydrochloric acid is carried out in a sealed headspace vial, and the carbon dioxide formed from the neutralization reaction, the self-decomposition of carbonic acid, and dissolved carbon dioxide in environmental wat… Show more

“…To obtain the vapor‐liquid equilibrium in the headspace vials before HS‐GC analysis, the effects of equilibration temperature and time were investigated for the wheat hydrolysate sample. According to the literature, [19,21] the vapor‐liquid equilibrium partition coefficient can be greatly affected by the temperature. Figure 4 shows the normalized GC signals (i. e., set the maximum signal under different testing conditions as one) of furfural after a 5 min equilibrium time at different temperatures (65, 75, 85, 95, 105 and 115 °C).…”

“…In contrast to traditional methods, headspace GC (HS-GC) is an effective technique for the analysis of volatiles in complex matrices. Several HS-GC methods have been developed to quantify analyte contents, such as dissolved inorganic carbon in environmental water [10], anhydride groups in anhydride-based epoxy hardeners [11], softening point of rosin [12], and hydrogen peroxide in pulp bleaching effluents [13]. A pressure-affected method for determining the CaCO 3 content of paper materials has been proposed [14].…”

“…Headspace (HS) GC has been proven to be an efficient tool in quantitatively analyzing volatile substances in the samples having complex matrixes [14][15][16][17][18][19][20]. The main advantage in HS-GC technique is that it can be performed at a precisely controlled temperature [21,22].…”
