Coastal Biogeochemistry Recharge Center
The Coastal Biogeochemistry Recharge Center offers laboratory analysis to internal and external clients. Full-service rates include instrument setup, sample preparation, sample analysis, data processing, and supplies. The minimum rate covers supplies only. Final costs depend on the technical support required, and pricing can accommodate project budgets. Students may participate for hands-on experience. The rates below are per sample and remain in effect through July 2027; they may change if supply costs change.
For scheduling, details, and questions, contact Quinn Roberts, laboratory manager.
Dissolved inorganic carbon analysis
The Apollo Dissolved Inorganic Carbon (DIC) Analyzer with LI-7815 measures dissolved inorganic carbon in fresh, brackish, and marine water samples. It acidifies a sample to release carbon dioxide (CO2) gas, which the gas analyzer detects and measures.
| Cost component | Internal | External |
|---|---|---|
| Supplies (minimum rate) | $0.72 | $0.85 |
| Instrument preparation | $0.51 | $0.60 |
| Sample preparation | $0.25 | $0.30 |
| Sample analysis | $5.09 | $6.00 |
| Data analysis | $0.25 | $0.30 |
| Full-service total | $6.82 | $8.05 |
Dissolved organic carbon and total nitrogen analysis
The Shimadzu TOC-LCSH/TNM analyzer measures non-purgeable dissolved organic carbon (DOC) and total nitrogen (TN) in filtered fresh, brackish, and marine water samples. Samples are acidified and sparged to remove carbon dioxide, then combusted at high temperature. DOC is measured with a nondispersive infrared sensor and TN with a chemiluminescence detector.
| Cost component | Internal | External |
|---|---|---|
| Supplies (minimum rate) | $2.48 | $2.93 |
| Instrument preparation | $1.27 | $1.50 |
| Sample preparation | $5.09 | $6.00 |
| Sample analysis | $5.09 | $6.00 |
| Data analysis | $1.27 | $1.50 |
| Full-service total | $15.20 | $17.93 |
Elemental analysis and nutrient analysis are also available. Contact Quinn Roberts for details.
