This study developed a method to quantify nine volatile sulfur compounds in biogas and sewage samples using solid-phase microextraction and GC-MS. The method proved effective, except for hydrogen sulfide, with no sample loss during 20-hour storage.

Area of Science:

  • Environmental Chemistry
  • Analytical Chemistry

Background:

  • Volatile sulfur compounds (VSCs) are key indicators in biogas and sewage treatment.
  • Accurate quantification of VSCs in complex matrices is challenging.

Purpose of the Study:

  • To assess procedures for quantifying nine VSCs in biogas and sewage plant samples.
  • To evaluate the effectiveness of solid-phase microextraction (SPME) and GC-MS for VSC analysis.

Main Methods:

  • Solid-phase microextraction (SPME) with a 75-microm Carboxen-polydimethylsiloxane fiber at 22°C for 20 min.
  • Gas chromatography-mass spectrometry (GC-MS) analysis.
  • Standard additions method to assess matrix effects.

Main Results:

  • Detection limits ranged from 1 pptv (carbon disulfide) to 470 pptv (hydrogen sulfide).

  • Matrix effects were observed but standard addition curves remained linear, allowing quantification of most VSCs.
  • No detectable VSC losses occurred during 20-hour storage in Tedlar bags, though humidity increased.

    • Conclusions:

    • The developed SPME-GC-MS procedure is suitable for quantifying multiple VSCs in complex environmental samples.
    • Hydrogen sulfide quantification requires further method optimization due to observed limitations.
    • CaCl2 as a drying agent did not impact VSC stability during sample storage.
