ABSTRACT:
Apparatus and method for extracting a component from a sample across a membrane into an extractant and then injecting the extracted sample component into a chromatographic eluent and onto a chromatographic column to chromatographically analyze the extracted sample component. In essence, the advance provided by this invention is that the extractant and the eluent are the same and only one pump is used for pumping the eluent and extractant. In prior apparatus and methods in this field, the extractant and the eluent were separate and each had its own pump.
