Abstract In 2009, the Commission on Isotopic Abundances and Atomic Weights (CIAAW) of the International Union of Pure and Applied Chemistry (IUPAC) introduced the interval notation to express the standard atomic weights of elements whose isotopic composition varies significantly in nature. However, it has become apparent that additional guidance would be helpful on how representative values should be derived from these intervals, and on how the associated uncertainty should be characterized and…

Interpretation and use of standard atomic weights (IUPAC Technical Report)

Abstract Many calculations for science or trade require the evaluation and propagation of measurement uncertainty. Although relative atomic masses (standard atomic weights) of elements in normal

The Table of Standard Atomic Weights—An exercise in consensus

The Commission shielded users of the TSAW and TICE from unreliable measurements that appear in the literature as a result of unduly small uncertainties, but the aim of IUPAC has been fulfilled by which any scientist can expect their sample atomic weight to lie within Ar (E) ± its uncertainty almost all of the time.

Standard atomic weights of the elements 2021 (IUPAC Technical Report)

Abstract Following the reviews of atomic-weight determinations and other cognate data in 2015, 2017, 2019 and 2021, the IUPAC (International Union of Pure and Applied Chemistry) Commission on

Redefinition of the basic units of the International System of Units (SI) — the kilogram, mole, ampere, and kelvin, — which are now expressed in terms of fundamental physical constants means a

An improved program for the estimation of protein theoretical relative molecular mass and uncertainty.

The NIST Mass Calculator is a software tool which provides both a relative molecular mass value (Mr) and an associated uncertainty value of a given protein sequence and is now a useful feature in light of the high resolution capability now available in the mass spectrometry of intact proteins.

The IUPAC Commission on Isotopic Abundances and Atomic Weights has changed the way certain atomic weights are reported, replacing the fixed ‘standard atomic weight’ with an atomic weight ‘interval’ for ten predominantly light elements, reflecting the variability of their isotopic composition.

C calibration of the reference gas relative to O2 released from primary standards (VSMOW2, SLAP2) in the same laboratory is highly recommended and non-linearity of the mass spectrometer may not only affect δ17O and δ18O values but also Δ'17O values, and the VSMOW-SLAP2 scaling should also be applied to analyses of rocks and minerals.
