Abstract:
1. A flow assisted-solid phase microextraction/gas chromatography-mass spectrometry (FA-SPME/GC-MS) system, comprising: a sample container comprising a sample solution comprising an aqueous solution and analytes; a first tube that connects the sample container and a pump and transports the sample solution to the pump; a second tube that transports sample solution to an extraction vial; an autosampler that uses the extraction vial to extract an aliquotted sample through an automated SPME method to determine the chloroether content in the aliquotted sample; a gas-chromatograph that desorbs the SPME fiber and determines the content of one or more chloroethers in the aliquotted sample; and a third tube that circulates the aliquotted sample from the extraction vial to the sample container.
