IODP Expedition 395C 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.采用离子色谱（ion chromatography）结合电导检测器（conductivity detector），对孔隙水样品中的阴、阳离子浓度进行了测定。待测阳离子包括钙、镁、钾和钠，待测阴离子包括氯离子、硫酸根和溴离子。
