Laboratory of Carbon Chemistry


Group members: Dr. Rodrigo Torres, Dr. Giovanni Daneri.

Within the line of research in Aquatic Ecosystems of the CIEP (Research Line I) various types of chemical analyses are done to study the carbon flow in its different chemical forms for studies in marine waters, but also for applications in continental and subterranean waters, and in the gaseous interchange of soils.  This laboratory has the capacity to measure CO2 (g), Dissolved Inorganic Carbon (DIC), Dissolved Organic Carbon (DOC), Particulate Inorganic Carbon (PIC), Particulate Organic Carbon (POC), as well as other parameters associated with carbon chemistry: pH and Total Alkalinity (TA).  These analyses also permit calculating other parameters that facilitate our understanding of the chemistry of carbon in aquatic systems such as the state of calcium carbonate saturation for calcite and aragonite (Omega).  Dr. Torres does the research in Dynamics of Inorganic Carbon (DIC, pH, TA, CO2), and Dr. Danneri does research in Dynamics of Organic Carbon (DOC, POC).  This laboratory is one of the best implemented of its type in the country and it supports various research projects in the context of eutrophication, marine metabolism, climate change, and ocean acidification.  For this purpose, the Laboratory of Carbon Chemistry is equipped with highly-sophisticated instrumentation such as Infrared Gas Analyzers for the measurement of CO2 and DIC, systems of automatic titration for the measurement of TA, potentiometric and spectrophotometric systems for the measurement of pH, systems for the measurement of COD (TOC) and for COP (CHN).

News:  The laboratory has vacancies for students working on their graduate or post-graduate theses in the subject of aquatic carbonate systems (i.e. metabolism, acidification of the ocean, etc.). Please send enquiries or requests to: Dr. Rodrigo Torres.
