|Detection by||Magnetic Sector ICP-MS||Description||
This method is used for the measurement of dissolved 232Th, 230Th, and 231Pa from water samples. Samples are collected in acid-cleaned 5-liter cubitainers, and acidified at sea to pH=2 using Optima grade 6M hydrochloric acid. The following method is for radionuclide analysis once the samples have been returned to Lamont-Doherty. This procedure is for analyzing one batch – which includes 15 samples, 2 procedural blanks, 2 seawater standards, and one column blank.
