• A conventional silicate line utilising ClF₃ with 10 nickel reaction vessels for the analysis of O in silicate rocks and minerals. The δ¹⁸O values are determined on O₂ gas absorbed onto molecular sieve in sample bottles
• A carbonate line for the extraction of CO₂ in carbonate rocks and minerals using 100% phosphoric acid. This line is also used to determine oxygen isotope values in water samples. Routine carbonate and water samples are analysed at the BIOGRIP facilities in the Dept of Archaeology across the road (carbonates) or the Soil Science Node at Stellenbosch University.
• A hydrogen line for the analysis of H in rocks and mineral samples and water samples
• A laser fluorination line for the analysis of 1-2 mg mineral samples using BrF₅. The δ¹⁸O values are determined on O2 gas absorbed onto molecular sieve in sample bottles.

All samples are analysed using either a DeltaXP or a DeltaPlus Advantage dual inlet gas source mass spectrometer housed in the Department of Archaeology. Please contact Chris Harris (details below) for information on rates for work in the stable isotope laboratory. As of 2024, Chris Harris will be semi-retired and more selective about work that with the work he will do. He is specifically interested in mantle rocks and intra-plate igneous rocks.
