AB  - An analytical method involving solid-phase micro-extraction (SPME) and gas 
      chromatography-mass spectrometry (GC-MS) was applied to analyze biosolids odors. 
      A selective ion monitoring (SIM)-based MS method was developed, using SPME 
      injections of odorant standards under the full-scan mode to select the 
      quantification and confirmation ions for each odorant. The odorants analyzed in 
      this study include: dimethylsulfide, dimethyldisulfide, methyl mercaptan, 
      hydrogen sulfide, carbon disulfide, trimethylamine and dimethylamine. We have 
      used this method to quantify parts-per-billion levels of odorant vapors produced 
      during anaerobic incubation of digested wastewater sludge. Important 
      considerations for expedient and accurate calibration under static and dynamic 
      flow conditions are discussed. The SPME-GC-MS method may give a positive 
      intercept in the calibration curve, especially under static sampling conditions, 
      which sets a practical detection limit for odor analysis.
