IODP Expedition 396 Ion chromatography

Cation and anion concentration in interstitial water samples was measured by ion chromatography using a conductivity detector. Cation analytes include calcium, magnesium, potassium, and sodium. Anion analytes include chloride, sulfate, and bromide.间隙水样品中的阴、阳离子浓度采用离子色谱法（ion chromatography）结合电导检测器（conductivity detector）进行测定。阳离子分析物包括钙、镁、钾与钠；阴离子分析物则包含氯化物、硫酸盐与溴化物。
