New Method of Analysis by Mass Spectrometry

Analytical Mass Spectrometry Utillizing Relative Abundance Ratios

“…Concentration of component, A (or B) versus the ratio of ion currents from selected masses. 2. Ratio of concentration of components A/B versus the ratio of ion currents from selected masses.…”

Compound Types in Gasoline by Mass Spectrometer Analysis

“…A NUMBER of laboratories throughout this country use commercial model mass spectrometers to obtain high precision analyses on a wide variety of organic compound mixtures (6,7,10,12,14). Notable success has been achieved in the field of hydrocarbon analysis, where very small samples containing up to thirty components can be analyzed in 1 or 2 man-hours (2,3,16).…”
