  • High accuracy determination of chlorine content by isotope dilution flame infrared emission spectrometry (ID-FIRE)
    Patent number: 5696378
    Abstract: A method and apparatus for quantitatively determining chlorine content and fractional abundance of chlorine isotopes in unknown samples. When using this method and apparatus to determine chlorine content, isotope dilution principles may be employed. Chlorine isotopes used for diluting an unknown sample may be .sup.35 Cl or .sup.37 Cl, and relative isotope content in the diluted mixture may be measured using infrared spectrometry.
