| Popis: | 1. Optimum conditions have been selected for gas-chromatographic determination of water in liquid samples, using a porous polymer, Polysorb 1. The analysis is performed with an LKhM-7A instrument with a thermal conductivity detector in helium; the Chromatographic column is back-flushed. 2. A formula is proposed for calculating the amount of water in test samples when using a calibration fluid containing water. The formula may be used for the determination of water in products of any consistency. 3. The sensitivity of the method is 10−4%, and the time required for analysis is 12–15 min. |
