Concept
Enrichment (with respect to 143Nd/144Nd in the CHondritic Uniform Reservoir (CHUR)) of neodymium-143 {143Nd} in the water body [dissolved plus reactive particulate <0.45um phase] by filtration and thermal ionization mass spectrometry

| Definition | The isotopic enrichment of 143Nd is calculated using the epsilon notation defined as epsilon Nd =([143Nd/144Nd] sample / [143Nd/144Nd] CHUR -1) x 10000). One epsilon unit represents a one part per 10,000 deviation from the CHUR composition. | |
