¹⁸O and H/D Analysis of Solids by TC/EA-IRMS

The SIF provides ¹⁸O or H/D isotope analyses of solid samples using a TC/EA system interfaced to IRMS.

Analysis

H/D and ¹⁸O are analyzed separately. If both analyses are needed, duplicate sets of samples must be sent. Solids are analyzed for ¹⁸O or H/D isotopes using a Heckatech HT Oxygen Analyzer interfaced to a PDZ Europa 20-20 isotope ratio mass spectrometer (Sercon Ltd., Cheshire, UK). Samples are combusted in a glassy carbon reactor at 1400°C to CO and H₂O. Oxygen is analyzed as CO, and H/D is analyzed as H₂.

Sample preparation

Weigh samples into silver capsules (3.5 x 5.0 mm) and organize into a clean 96-well plate. Use separate trays for each analysis type. Ensure samples stay in the wells during shipping by placing an index card (cut to size) or Parafilm over the plate before securing the lid. Do not use adhesive films to cover the open wells. Tape the lid securely closed. Carefully package in a rigid box filled with packing material.

Analysis Order Form

Please include an Analysis Order Form with any samples you deliver to the Stable Isotope Facility. The SIF uses this form to track your samples and to contact you regarding receipt of samples, data, and invoicing. For mixed analysis requests, we recommend completing a separate form for each type of analysis.
