Advanced capillary sampling technique for spatially resolved analysis of complex gas mixtures

Key Points

• This research aims to investigate the spatial distribution of gas-phase species in structured catalysts.
• Adapted an invasive capillary-based sampling method for complex gas environments.
• Conducted spatial analysis within the catalysts under realistic exhaust conditions.
• Analysis showed how gas-phase species are distributed within the structured catalysts.
• The method effectively captures the spatial characteristics of gas mixtures in real exhaust scenarios.
