Dr Chris Stopford

University of Hertfordshire

Dr Chris Stopford is a physicist from the University of Hertfordshire, who leads the Particle Instruments & Diagnostics research team in developing new and novel instruments for the real-time detection, sizing, and classification of airborne particulates. His work began with meteorological measurements of microscopic cirrus cloud ice crystals; working with & developing aircraft-borne instruments.

More recently he has focused on solving the problem of low-cost detection of respirable hazards. Working with industry, a number of ground-breaking devices have successfully been developed, tested, and brought to market to detect airborne asbestos, crystalline silica, biological hazards and PM pollutants.

Real-time Detection & Characterisation of Airborne Hazards

Laser optical techniques are used to detect and characterise particles in real-time. This technology has been used to identify airborne asbestos, respirable crystalline silica, biological hazards, and general PM measurements at low-cost. I will discuss the current state of the art, and future potential for this technology.
