Kolloid- ja pindnähtuste keemia
liquid or gas colloid. A nephelometer measures suspended particulates by employing a light beam (source beam)
and a light detector set to one side (often 90°) of the source beam. Particle density is then a function of the light
reflected into the detector from the particles. To some extent, how much light reflects for a given density of
particles is dependent upon properties of the particles such as their shape, color, and reflectivity. Nephelometers
are calibrated to a known particulate, then use environmental factors (k-factors) to compensate lighter or darker
colored dusts accordingly. K-factor is determined by the user by running the nephelometer next to an air sampling
pump and comparing results.
