XRF APPLICATION NOTE: Automotive Catalyst

Motor vehicle catalytic converters provide an environment for chemical reactions in which toxic combustion by-products such as nitrous oxides, carbon monoxide and unburnt hydrocarbons are converted to safe or less toxic substances including oxygen, nitrogen, water vapor and carbon dioxide. A refractory ceramic monolith with a honeycomb structure forms the core of the converter to […]

STRATEGY OF FUSION BEAD CORRECTION IN XRF ANALYSIS OF POWDERS

The fusion bead method is an effective sample preparation technique for accurate analysis of a wide variety of powder samples by XRF spectrometry such as ores, rocks and refractory materials since it eliminates heterogeneity effects associated with grain size and mineralogical composition. In order to obtain highly accurate results, it is necessary to provide a […]
