It was therefore used in a pilot experiment on the inorganic component of CO 2 flows from crusted semi-arid soils, and to evaluate the variation in DIC content through a spring-cave-downstream river water continuum. The new instrument proved to be sensitive, accurate, precise and able to quickly perform the analyses.
By taking advantage of the recent development of low-cost CO 2 sensors and microcontrollers, a low-cost and easy-to-mount analyzer was developed based on direct measurements of CO 2 evolved during an acidic reaction. To tackle this problem, we aimed to develop a sensitive device to measure these variables at low cost and with little time investment.However, most methods currently available to accurately measure these parameters can be time-consuming and/or often require expensive laboratory equipment. Geochemical models used to estimate carbonate precipitation–dissolution rates require important inputs including carbonate content and calcite reactive surface area in soil as well as dissolved inorganic carbon (DIC) content in soil solution. Estimates of soil carbonate dynamics are still very scarce, despite their importance in the global carbon budget.
