SOLVENTEXTRAKTIONSSYSTEM

摘要

Methods for the solvent extraction of organic analytes from a sample are provided. An organic solvent system is used to extract analytes under elevated temperatures and pressures above 100 psi but below supercritical conditions in short times and with low amounts of solvent. The extracted organic analytes are then removed by flowing a purge fluid through the extraction cell, the cell being maintained at a constant volume throughout the extraction and purging, afterwards the analytes being analyzed.
