IODP Expedition 397 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（interstitial water）样品中的阴阳离子浓度采用配备电导检测器（conductivity detector）的离子色谱法（ion chromatography）进行测定。阳离子分析物（cation analytes）包括钙、镁、钾和钠；阴离子分析物（anion analytes）则涵盖氯离子、硫酸根离子和溴离子。
