Chemical composition of hydrothermal fluids at station MSM04/3-275-ROV-8@en

Inductively Coupled Plasma Mass Spectrometry: dilution factor = 25; Matrix = 0.5M HNO3. Inductively Coupled Plasma Optical Emission Spectrometry: dilution factor = 10; Matrix = 0.5M HNO3. Preconcentration with ion exchange resin for Y and REE, followed by ICP-MS measurement (Bau and Dulski, 1996).电感耦合等离子体质谱法（Inductively Coupled Plasma Mass Spectrometry，ICP-MS）：稀释因子为25；基体为0.5M硝酸。电感耦合等离子体光发射光谱法（Inductively Coupled Plasma Optical Emission Spectrometry，ICP-OES）：稀释因子为10；基体为0.5M硝酸。采用离子交换树脂对钇（Y）与稀土元素（REE）进行预富集，随后采用ICP-MS进行测定（Bau与Dulski，1996）。
