GAS-LIQUID CONTACT EXTRACTION METHOD AND APPARATUS |
摘要 |
The present invention provides a method and apparatus for rapidly extracting the analyte existing in the liquid phase in analyzing an analyse “having a large partition coefficient in gas-liquid equilibrium”, “having a high water solubility”, or “having a low olfactory threshold” by a gas-liquid contact extraction method, and further provides, a method and apparatus for unmanned continuous sample introduction of the analyte to a GC or the like for a long time. In the present invention, using a gas-liquid contact extractor to which a sample liquid is continuously introduced from above and a purge gas from beneath, the analyte in the sample liquid is extracted by gas-liquid contact between the sample liquid and the purge gas. A discharge pipe is connected to the bottom of the gas-liquid contact extractor, the pipe having a liquid sump through which the sample liquid is discharged, while blocking the outflow of the purge gas from the liquid sump. |

1. A gas-liquid contact extraction method using a gas-liquid contact extractor to which a sample liquid is continuously introduced from above and a purge gas from beneath, for extracting an analyte in the sample liquid by gas-liquid contact between the sample liquid and the purge gas, the method comprising discharging the sample liquid through a liquid sump provided to a discharge pipe connected to a bottom of the gas-liquid contact extractor, while blocking outflow of the purge gas from the liquid sump. |
