Concept
Enrichment with respect to 143Nd/144Nd in the CHondritic Uniform Reservoir (CHUR) of neodymium-143 {143Nd CAS 14336-83-5} {epsilon Nd value} in the water body [dissolved plus reactive particulate <0.2um phase] by filtration and thermal ionization mass spectrometry

| Definition | The isotope ratio of 143Nd/144Nd expressed 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. | |
