IODP Expedition 342 Titration

Various chemical constituents (most commonly chloride) were measured by titration using either an autotitrator (chloride) or a manual titrator (other compounds). Chloride was measured by ion-selective electrode and a silver nitrate titration until all chloride is bound as silver chloride.该数据集通过滴定法对多种化学成分展开检测，其中最常见的检测对象为氯离子（chloride）：针对氯离子采用自动滴定仪（autotitrator），针对其余化合物则采用手动滴定仪（manual titrator）。氯离子的具体检测方法为离子选择性电极结合硝酸银滴定法，直至所有氯离子均结合为氯化银（silver chloride）沉淀。
