We routinely analyze the following substances:

• Solids: Bulk analysis of solids (and some fluids) for δ¹³C, δ¹⁵N, δ³⁴S via thermal decomposition. This includes e.g., soil and rock samples, organic substances, inorganic substances like sulfates, nitrates, or sulfides. Using our high temperature pyrolysis system, we also routinely measure δ¹⁸O on nitrates, sulfates, silicates. These measurement typically requires 10 to 20 mug of e.g. N or C etc. The achievable precision depends on the actual material. Typical σ-values range from 0.1 to 0.4 per mil.
• Gases: Our mass spectrometer is equipped with a 6 cup collector, enabling us to measure the isotopic composition of the following gas-species:  CO₂, CO, SO₂, O₂, N₂, SF₆,
Extractions and TC/TOC determinations: Upon request, we perform sulfur extraction and conversion to BaSO₄ and Ag₂S. We also perform total carbon (TC) and total organic carbon (TOC) determinations, on samples with less than 20wt% CaCO₃ content. Please contact us for a quote.
