| Brief Description: |
Coulometer for DIC analyses (does not include sample handling or gas extraction); Repeatability of ±0.019% (152.30 ± 0.03 μg C; n=58) was attained when successively analyzing the ~30cm3 of 1% CO2 in air (at T / K =293.15 and P / hPa =1013.25). Repeatability of ±0.6 μmol kg-1 was estimated from 188 pairs of replicate analyses on board R/V Mirai during its WHP P21 cruise conducted in 2009. |
