The determination of 235-u by the isotope dilution method

Analytica Chimica Acta, 1960
Summary This paper describes an examination of the precision which might be achieved by using an isotopic dilution method for the determination of 235U in the feed solution of an enriched uranium fuel chemical processing plant such as the Dounreay M.T.R. chemical plant.

Calculation of precision in isotope dilution experiments

The International Journal of Applied Radiation and Isotopes, 1969
Abstract Equations are derived for the composite error of isotope dilution measurements in three types of experiment viz. simple dilution, saturation analysis (sub-stoichiometric dilution) and adsorbed ion measurement; the latter two yielding equations of the same form.

Orientational dynamics of isotopically diluted H2O and D2O

The Journal of Chemical Physics, 2006
We use femtosecond midinfrared pump-probe spectroscopy to compare the ultrafast dynamics of HDO dissolved in D2O and H2O. For both systems the vibrational energy relaxation proceeds through an intermediate state. The relaxation leads to heating of the sample, which is observed in the transient spectra.

Isotope dilution mass spectrometry of cholesterol in serum

Biological Mass Spectrometry, 1981
Isotope dilution mass spectrometry is one of the best candidates for reference and definitive methods for the quantitative measurement of organic compounds. In this study sources of error were investigated. Where possible they were removed, and commercially available equipment had to be modified.

The determination of zinc by substoichiometric isotope dilution

Analytica Chimica Acta, 1966
Abstract Recently, RŮŽICKA et al. proposed a determination of zinc in highly pure germanium dioxide by a substoichiometric extraction technique. In the present work, the effects on the substoichiometric extraction of equilibrium time, pH and interfering ions were investigated by radioactive tracer techniques and spectrophotometric measurements.

The determination of inorganic sulfate by an isotope dilution technique

Clinica Chimica Acta, 1971
Abstract An isotope dilution method using 35SO42− for the determination of inorganic sulfate in urine is described. This method, based on a fractional precipitation of sulfate as BaSO4, has proven to be as accurate as currently used micro techniques and has the advantage of being simple, rapid, and especially well suited for assays of large numbers ...

The determination of nitrogen in metals by isotope dilution

Analytica Chimica Acta, 1959
Abstract A wet chemical procedure for determining the amount of nitrogen in a metal or alloy has been developed which utilizes the isotope dilution technique. Ammonium sulfate, either enriched or depleted in 15N, is added to the metal sample during solution procedures.
