Abstract
A review of methods for thermal desorption from concentrators in portable rapid gas chromatographs of the EKhO series for injecting samples of organic substances into a gas chromatographic column depending on the volatility range of substances in the samples is presented. Sample injection techniques without manual operations in EKhO instruments are considered. The principles of sample injection with incomplete gas-dynamic isolation of the injection chamber and the column when introducing explosive and arene vapor samples with different volatility of substances in the sample and with complete isolation of the injection chamber and the column when introducing samples of C1−C5 saturated hydrocarbons with sharply different volatility are described.
期刊介绍:
The Journal of Analytical Chemistry is an international peer reviewed journal that covers theoretical and applied aspects of analytical chemistry; it informs the reader about new achievements in analytical methods, instruments and reagents. Ample space is devoted to problems arising in the analysis of vital media such as water and air. Consideration is given to the detection and determination of metal ions, anions, and various organic substances. The journal welcomes manuscripts from all countries in the English or Russian language.
