Direct analysis of water samples for organic pollutants with gas chromatography-mass spectrometry
A direct aqueous injection gas chromatography-mass spectrometry (GC/MS) procedure was explored as a supplement to conventional solvent extraction for analysis of the organic pollutants in water and wastewater samples. Studies were made of the effects of relatively large pressures of water vapor on the well established electron impact fragmentation patters, quadrupole GC/MS system performance, interactive background subtraction, and detection limits. It was concluded that direct aqueous analysis is a valuable supplemental procedure for the detection of volatile compounds that are not found with solvent extraction.
