IODP Expedition 366 Spectrophotometry

Interstitial water constitutents were measured by UV-VIS spectrometry using colorimetric methods (e.g., ammonium, nitrate, nitrite, phosphate, silica, and sulfide) by an Agilent CARY 100 UV-VIS spectrophotometer.间隙水（interstitial water）组分的测定采用安捷伦CARY 100型紫外-可见分光光度计（Agilent CARY 100 UV-VIS spectrophotometer），通过紫外-可见分光光度法（UV-VIS spectrometry）结合比色法（colorimetric methods）完成，所检测的组分包括铵、硝酸根、亚硝酸根、磷酸根、硅（二氧化硅）以及硫化物。
