Concept

Enrichment with respect to 138Ba/134Ba in NIST SRM 3104a of barium-138 {138Ba CAS 15010-01-2} {delta(138)Ba} in the water body [dissolved plus reactive particulate <0.2um phase] by filtration, acidification and inductively-coupled plasma mass spectrometry

Definition	Deviation of the 138Ba/134Ba isotopic ratio of a sample of fresh or salt water after removal of particles larger than 0.2 micron relative to the standard solution SRM 3104a, a reference material for Barium (Ba) developed by the US National Institute of Standards and Technology, defined as delta(138/134Ba)NIST =([138Ba/134Ba]sample/[138Ba/134Ba]NIST)-1)×1000. One delta unit represents a one part per 1,000 deviation from the NIST standard composition.
