Analytical Research
and problem solving


University of East Anglia

My team at the University of East Anglia uses 2 coulometers model CM5011 for determining the total dissolved inorganic carbon concentration (known as TCO2, DIC, TC) in seawater. The coulometers are ~25 years old but are still performing well.

As a chemical oceanographer working on understanding impacts of ocean acidification on tropical coral reefs, measuring marine properties like Dissolved Inorganic Carbon (DIC) with high precision and accuracy, is vital for our research.

National oceanography center

We use two UIC coulometers for analyzing seawater samples for the accumulation of anthropogenic CO2 emissions throughout the water column (0- 6500m depth) across entire ocean basins (North/South Atlantic, Southern Ocean). We are constantly amazed at the precision and performance of the instruments.

This is our first experience (around 1 year of continuous use) using coulometric detection for carbon analysis, we were used only to the classic TOC analysis that uses NDIR detection. So far, I prefer coulometric detection! It’s faster, more precise, and trustworthy. What I like the most is the fact that it doesn’t need detector calibration like the NDIR detectors.
