IODP Expedition 402 Inorganic carbon (coulometer)

Inorganic carbon (carbonate) is determined by coulometry, which uses a photodetection cell to measure carbon dioxide evolved during sample acidification. Report includes percent inorganic carbon and calcium carbonate.无机碳（碳酸盐）的含量通过库仑法（coulometry）测定，该方法利用光电检测池（photodetection cell）对样品酸化过程中释放的二氧化碳进行检测。检测报告将包含无机碳百分含量与碳酸钙含量。
