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.

Oil, Extract, Fraction and Kerogen

• ¹³C/¹²C

• D/H

• ³⁴S/³²S

• ¹⁵N/¹⁴N

Water

• D/H and 18O/16O

• ³⁴S/³²S of Dissolved Sulfate or H₂S

• ³⁴S/³²S of Dissolved Sulfate or H₂S with %S

• 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

• ¹³C, ¹⁵N, ³⁴S, D/H

• C-14 of Carbonate or organic
