PoolDilutionR: An R package for easy optimization of isotope pool dilution calculations
Methods in Ecology and Evolution, 2023 Isotopic pool dilution is a powerful approach to quantify gross biogeochemical transformation rates, but remains seldom used despite its potential. To facilitate broader implementation of pool dilution methods, we present a user‐friendly R package that ...

13C Isotope Labelling to Follow the Flux of Photorespiratory Intermediates
Plants, 2021 Measuring the carbon flux through metabolic pathways in intact illuminated leaves remains challenging because of, e.g., isotopic dilution by endogenous metabolites, the impossibility to reach isotopic steady state, and the occurrence of multiple pools ...

Blank Correction in Isotope Dilution
Analytical Chemistry, 2015 A novel method for compensation of the procedural blank in isotope dilution is presented. This method, entitled "blank-matching", copes with the blank through experimental design. Both sample and calibration solutions are exposed to the same amount of isotopic standard and same procedural blank.

Solution to the isotope dilution challenge [PDF]
Analytical and Bioanalytical Chemistry, 2015 Over the years, isotope dilution mass spectrometry (IDMS) has witnessed many reformulations. One of the earliest expressions for this quantitation model was given by the single isotope dilution (IDMS). In IDMS, the mass fraction of an analyte A is obtained from mass spectrometric analysis of a mixture (blend) of sample and an isotopically-enriched form
