A system for determination of intra catalyst reactor chemistry

Measures the real-time concentration of gases inside a catalyst monolith

Spaci-MS allows both radial and axial species determination and temperature profiles, with high spatial and temporal resolution and with negligible interference in flow or temperature. The 16 channel multi-inlet is coupled to Hiden’s fast transient MS to provide automatic and rapid mapping of temperature and species distributions.

Overview

The Hiden Analytical spatially resolved capillary inlet MS (Spaci-MS) is the first commercially available instrument of its kind.

The Spaci-MS inlet was originally conceived and developed by researchers at the Oak Ridge National Laboratory and Cummins, Inc. to study diesel catalysis (1) and has been further developed for a whole range of applications.

The 16 capillary sampling probes and thermocouples are arranged in an X-Y array. A Z-shift provides movement and accurate positioning of the array in the Z plane. In usual practice, the 16 capillary sampling probes are sequentially analysed by the MS. The Z-shift is then actuated to move the sampling probe array to the next incremental Z position and the analysis sequence is repeated. On completion the analytical data provides a spatial representation of temperature and sample gas composition of the volume enclosed within the X-Y array over the total incremental Z distance moved.
