Development of an advanced on-line position-specific stable carbon isotope system and application to methyl tert-butyl ether [PDF]

, 2009
We present an advanced system for on-line position-specific carbon isotope analysis. The main limitation of on-line intramolecular isotope ratio measurements has been that optimal pyrolytic fragments are obtained mostly at temperatures where the analyte ...
