δ13C and 14C of Dissolved Inorganic Carbon


δ13C of DIC: Water samples are acidified and analyzed via a Gas Bench and CF-IRMS

Sample size: minimum-25 mL, ideal-150 mL. If you require analysis on smaller volumes please contact us.

Sample Container: HDPE (plastic) or glass bottle. Plastic is preferred for shipping safety. The sample should not have air included in the bottle.

Preservative: Filter the sample with at least a 0.45 micron or smaller pore-size diameter filter. The sample should also be kept on ice to minimize any microbial action.

Expected Turnaround Time:
Standard Service 15 business days
Rush Service* 5 business days
*Advance arrangements required for RUSH SERVICE

14C of DIC: Water is acidified and the resulting carbon dioxide is collected and sent to Beta Analytic for AMS analysis. Results are reported in percent modern carbon (pMC).

Sample size: minimum-70 mL, ideal-250 mL. If you require analysis on smaller volumes please contact us.
