Evaluating the Carbonation of Concrete by TOC Solid Sample Measurement System
Reducing carbon dioxide (CO2) emissions is a global challenge, and various efforts are underway in various industries to achieve carbon neutrality. In the construction industry, the manufacturing process of cement, a material used in concrete, emits a large amount of CO2, so its constituent materials and manufacturing process are being reviewed. Among such efforts, the development of a new concrete that captures CO2 emitted into the atmosphere and absorbs it is attracting attention. In addition to reducing the amount of cement used, the use of materials that absorb CO2 is expected to significantly reduce CO2 emissions, as concrete materials can be mixed with CO2-absorbing admixtures to affix CO2 as a carbonate in the concrete.
Total Organic Carbon Analyzer
The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation method, which was developed by Shimadzu and is now used worldwide. While providing an ultra wide range of 4 μg/L to 30,000 mg/L, these analyzers boast a detection limit of 4 μg/L through coordination with NDIR.
Solid Sample Combustion Unit
When combined with the TOC-L series, TC, IC, and TOC measurements can be performed in soil, sludge, sedimentation, and other solid samples. In addition, with GMP cleaning validation, the system can also be used to evaluate residues using the swab sampling/direct combustion carbon analysis method.
