The chromatomass-spectrometry method was for the first time employed to study organic substances isolated by vapour-phase extraction from the Matseta sulfide-containing mineral water near Sochi. These substances are found to contain sulphur in different valent forms. A new technique has been developed for the detection of monobasic C2-C6 carboxylic acids in natural mineral water based on the combination of sequential vapour extraction and extractive freezing of the analytes. The proposed method is readily reproducible and has a detection limit of 0.03 mg/l for the analysis of carboxylic acids in water.
首次采用色质联用分析法研究从索契附近的马特塞塔含硫化物矿泉水中通过气相萃取分离出的有机物质。发现这些物质含有不同价态的硫。基于对分析物的连续蒸汽萃取和萃取冷冻相结合，开发了一种用于检测天然矿泉水中一元C2 - C6羧酸的新技术。所提出的方法易于重现，用于分析水中羧酸时的检测限为0.03毫克/升。
