ABSTRACT:
The present invention pertains to an apparatus for gathering analyte. The apparatus comprises a pumping mechanism for pumping solvent at supercritical pressure. The apparatus also comprises an extraction mechanism which receives a first sample and at least a second sample separate and distinct from the first sample and extract analyte from them essentially simultaneously. The extraction mechanism is connected to the pump mechanism to receive solvent at supercritical pressure for extracting the analyte from the samples. The apparatus additionally comprises a collection mechanism for collecting analyte from the solvent after the analyte has been extracted from the samples. The collection mechanism receives the supercritical solvent having the analyte extracted from the samples from the extraction mechanism. The present invention pertains to a method for extracting analyte. The method comprises the steps of pumping solvent at a supercritical pressure. Then there is the step of extracting analyte from N samples essentially simultaneously with the solvent at a supercritical pressure, where N is greater than or equal to two and is an integer. The N samples are separate and distinct from each other. Then there is the step of collecting the analyte of the N samples from the solvent.
