摘要： The present invention is devoted to an analytical method for directly determining carbon number and molecular weight distributions of isoparaffin mixtures. The analytical means uses low in-scan emitter-current field-ionization mass spectroscopy to substantially reduced or eliminated molecular ion fragmentation for isoparaffins, which allows direct measurement of isoparaffin molecular ions for their distributions. The analytical means is capable of directly characterizing isobutane to C50+ isoparaffins, covering naphtha to gas oil ranges.

摘要： The present invention is directed to a method for determining the halogen toxicity level in a sample containing halogenated compounds, specifically halogen containing rubbers by utilizing thermal electrons formed inside a mass spectrometer operated at negative ion electron capture conditions. The method allows for detection of the toxic species from the parts per million level, down to the parts per billion levels. The method comprises the steps of (a) ionizing a reagent gas capable of producing thermal electrons having a thermal energy of 0 to 10 eV with the a polychromatic ion source of a mass spectrometer to produce thermal electrons having thermal energy of 0 to 10 eV, (b) capturing said thermal electrons with a halogen containing compound to form halogen atomic anions or halogen atomic cluster anions wherein said halogen containing compound has been passed through a gas chromatograph prior to said capturing of thermal electrons and wherein a mass spectrogram is obtained following said capturing of electrons, (c) speciating and quantifying said halogen atomic anions or halogen atomic cluster anions using a mass chromatogram produced from a combination of said gas chromatography and said mass spectrometer.
