Abstract:
Oxygenates are critical markers of feedstock quality, process performance, and product stability across fuels, chemical recycling, and biobased materials. Yet their detection remains difficult. Complex matrices and diverse structures challenge traditional tools like O-FID and conventional MS, which often lack equimolarity, selectivity, or matrix robustness. This talk presents new data generated using the ELEM-SPOT™ system—a GC-Combustion-MS platform employing isotopically labeled oxygen (¹⁸O₂) during combustion for equimolar, compound-independent oxygen quantification. Coupled with full MS structural characterization, the approach enables both accurate quantitation and untargeted identification of oxygenates, offering new process insight and improved control for advanced fuel and chemical workflows.
