University of Leeds Aerosol Instrumentation and Measurement

The aerosol observation group has access to a wide range of instrumentation, some of which are commercially available systems, others which have been developed in house.  The instrumentation within the group was enhanced in 2003 when Emeritus Prof. Mike Smith received Science Research Investment Funding (SRIF) from the University.  This funding was used to establish the Environmental Chamber Laboratory, which houses the Environmental Chamber, some of the aerosol generation equipment detailed below, and the TSI Model 3800 Aerosol Time-Of-Flight Mass Spectrometer.  The laboratory is located a ten minute walk away from the main School building, in the School of Physics and Astronomy.
