SpaciMS.

The Hiden Analytical spatially resolved capillary inlet MS (SpaciMS) uses an inlet that was originally conceived and developed by researchers at the Oak Ridge National Laboratory and Cummins, Inc. to study diesel catalysis, and has been further developed for a whole range of applications.

SpaciMS 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 (HPR-20 TMS) to provide automatic and rapid mapping of temperature and species distributions.

Up to 16 capillary sampling probes and thermocouples are arranged in an X-Y array, and a Z-shift provides movement and accurate positioning of the array in the Z plane. On completion of the analysis sequence, the 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.
