MICROWAVE-ASSISTED HEADSPACE LIQUID-PHASE MICROEXTRACTION OF AN ANALYTE |
| 摘要 |
A method for extracting an analyte in a sample is described. A sample and a solution in a microwave-extraction vial are microwave-heated and agitated. A vapor produced in the vial can be extracted into a liquid-phase medium contained in a porous membrane bag situated in the vial. The liquid-phase medium containing the vapor extract may then be analyzed for an analyte with gas chromatography-mass spectrometry. |

1: A method for extracting an analyte in a sample comprising:
microwave-heating and agitating the sample and a solution in a microwave extraction assembly comprising:
a microwave extraction vial with a bottom portion and a headspace portion anda porous membrane bag located in the headspace portion of the microwave extraction vial, said porous membrane bag encapsulating a liquid-phase extraction medium, wherein the sample and solution are disposed in the bottom portion, the porous membrane bag does not contact the sample and the solution, and the microwave-heating and agitating produces a vapor in the headspace portion; and extracting the analyte from the vapor to produce a vapor extract within the liquid-phase extraction medium. |
