Chemical composition of hydrothermal fluids at station MSM04/3-271-ROV-11@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0.5mol/L硝酸。电感耦合等离子体发射光谱法（Inductively Coupled Plasma Optical Emission Spectrometry，ICP-OES）：稀释因子为10；基体为0.5mol/L硝酸。采用离子交换树脂对钇（Y）和稀土元素（Rare Earth Elements，REE）进行预富集，随后采用ICP-MS进行测定（Bau和Dulski，1996）。
