Sorby Laboratory investigates respirator fit to inform COVID-19 mask protocols

The research team at Sorby Environmental Fluid Dynamics Laboratory, School of Earth and Environment have repurposed their laboratory equipment for new COVID-19 related research.

The Sorby Laboratory team are investigating respirator fit to inform face mask protocols.  This is a new Sorby Environmental Fluid Dynamics Laboratory, School of Earth & Environment and School of Engineering collaboration at the University of Leeds.

A medium wave infrared camera (MWIR) was used to capture images of a human subject wearing various face masks. By using a special filter the MWIR camera becomes highly sensitive to optical adsorption of CO2 and allows visualization of CO2 at room temperature.

This short film illustrates these visualizations:
