  • Method for detecting and quantifying carbon isotopes
    Patent number: 4427884
    Abstract: A method for detecting and quantifying a carbon isotope at quantities of less than 1.times.10.sup.-12 gram at a statistical precision of better than 5% in a time period of less than 5 minutes by producing a carbon compound, selected from CO,CS.sub.2,CO.sub.2 and elemental carbon, from the carbon containing composition to be analyzed; and producing and detecting sufficient C.sup.- ions from the carbon compound at a known efficiency to provide at least 80 counts of carbon isotope ions per minute by mass spectrometry.
