  • Materials and methods for controlling isotope effects during fractionation of analytes
    Patent number: 7449170
    Abstract: Compositions and methods for controlling or eliminating isotope effects during fractionation of chemically equivalent but isotopically distinct compounds. Isotope coding agents contain heavy isotopes other than deuterium. The invention facilitates intelligent data acquisiton. After sample fractionation, isotope abundance ratios are calculated using mass spectrometry, and analytes of interest are identified in real time.
