Last quote by Chris Stopford

It is currently plugged into a laptop, which does all the data recording and manipulation. The screen is displaying the scattering pattern from every particle that goes through the instrument. Here it is quite dusty, but it is random dust rather than being fibres, so we are not seeing any asbestos fibres at all. The device works by bringing air into this inlet and into a chamber where a particle is illuminated first by one laser and the scattering pattern from that is captured and is then exposed to a magnetic field, which preferentially rotates asbestos fibres against non-asbestos fibres.

Chris Stopford has most recently been quoted in an article called Invisible at first sight. Chris Stopford said, “This fibre is about 1,000 times larger than an asbestos fibre. But when when we introduce it to a laser beam, it illuminates itself in exactly the same way as an asbestos fibre would, creating a very similar scattering pattern.”. Chris Stopford has been quoted a grand total of 4 times in 1 article.
