Gas
  • 13C/12C of Methane (c1), c2, c3, n-c4, I-c4 or Total c4
  • D/H of c1, c2, c3, n-c4, I-c4 or Total c4
  • 13C/12C of CO2
  • C-14 of Methane and CO2
  • 34S/32S of H2S
  • Composition Screen (H2S)
  • Composition Screen (CH4, CO2) Low hydrocabon concentrations (methane <0.5%) may require additional steps and involve a small surcharge. Gas composition is required for isotope analysis, and may be providedby the client or performed by DPRA-ZymaX.

  • 13C/12C of Dissolved CO2 (precipitation method)
  • 13C/12C of Solid Carbonate/Bicarbonate (Some carbonate minerals may need additional preparation and require additional cost.)
  • 15N/14N of Dissolved Nitrate and/or Ammonia
  • Cl-37 for Chloride or solvent
  • Compostion Screen (Nitrate and Ammonia) Nitrate and ammonia concentration is required for nitrate or ammonia isotope analysis, and may be provided by the client or performed by DPRA-ZymaX.

Soil and Minerals
