Computer Survey of GC/MS (Gas Chromatography/Mass Spectrometry) Data Acquired in EPA's (Environmental Protection Agency) Priority Pollutant Screening Analysis: System and Results

摘要

The screening analysis phase of the best available treatment (BAT) review of wastewater treatment techniques by EPA was initiated to assess 21 industrial categories for the 129 'priority pollutants.' Implicit in the purpose of the screening analysis for these pollutants was the notion that the raw GC/MS data would be saved for later evaluation for compounds not on the priority pollutant list. To this end, a system of computer programs was built that automatically extracts the pure spectra of components in a GC/MS run, matches these spectra against a reference library, and deals appropriately with matched and unmatched spectra.
