Atmospheric Chemistry: HIRAC Group

The Highly Instrumented Reactor for Atmospheric Chemistry (HIRAC) is a NERC funded atmospheric simulation chamber developed to bridge the divide between the study of elementary reactions in the lab, and large scale field work. Unlike any other atmospheric simulation chambers HIRAC allows researchers the unique ability to control temperature, pressure and photolysis rates during experiments.

Just as the name suggests, HIRAC has a broad range of instrumentation based on different detection techniques so that we can accurately monitor the chemistry occurring inside the chamber. HIRAC has been funded to carry out a number of exciting and novel experiments to answer some of the important questions remaining in atmospheric chemistry. We also plan to use the chamber to test and develop field measurement techniques.

HIRAC is a member of the EUROCHAMP (Integration of European Simulation Chambers for Investigating Atmospheric Processes) network of European chambers.

New dedicated laser

Thanks to investment from the School of Chemistry and the University, we have just received delivery of a new higher powered laser dedicated to HIRAC. This should significantly increase the productivity of HIRAC and the sensitivity of the HIRAC FAGE instrument. The laser provides sufficient power such that the excess can be used for the OH reactivity instrument and to light the department....

    

International Symposium on Gas Kinetics and Related Phenomena, Szeged, July 2014

Four posters from the HIRAC group were presented and well received at the recent gas kinetics conference in Szeged, Hungary, covering instrument development, mechanistic studies on isoprene oxidation and RO2 chemistry, and on relative rate kinetics studies. Copies of the posters can be found in the poster section.
