Organic micropollutants in air and water

摘要: Abstract Organic micropollutants are sampled by dynamic enrichment on a porous polymer column and subsequently thermally eluted in flow of helium. The compounds enter gas chromatograph inlet then pass into two parallel glass capillary columns with different stationary phases, which they separated. separated detected chromatographic (GC) detectors mass spectrometer that is connected to one or other the “heart cutting” systems.
