Abstract

Rapid screening for activities and selectivities of catalyst libraries having addressable test sites is achieved by contacting potential catalysts at the test sites with reactant streams forming product plumes at the addressable test sites. The product plumes are screened by translating a sample probe (108) and/or the library to a position that one addressable site is in proximity to the sampling probe sample orifice (117) and passing a portion of the reaction products through the sampling orifice forming a free jet expanded volume in at least one vacuum stage and passing a portion of the cooled and reduced pressure jet stream through an inlet orifice of a mass spectrometer for analysis. The mass spectrometric analysis may be combined with resonance enhanced multi-photon ionisation methods of detection for very rapid library evaluation. Suitable reactors, micro-reactors, and product transfer sample microprobes for product transfer to a mass spectrometer are disclosed.
