Imaging reflection IR spectroscopy as a tool to achieve higher integration for high-throughput experimentation in catalysis research.

Abstract

FTIR spectroscopy in reflection mode combined with a focal plane array (FPA) detector was employed for high-throughput screening of activity of catalysts in n-pentane hydroisomerization. The reactor system was evaluated using reference catalysts Pt-MOR and gamma-alumina of known catalytic activity. By using the reflection setup, a higher degree of parallelization was possible, as compared to previous reports, in which transmission cells had been used. The 49-channel parallel reactor in combination with the FPA-IR optical setup was able to provide reliable information about the activity of different catalysts with relative data error of less than +/-20%.
