When electromagnetic radiation light strikes on a particle in solution, some of the light will be absorbed by the particle, some will be transmitted through the solution and some of the light will be scattered or reflected. Nephlometry and turbidimetry ppt authorstream presentation. The components of a nephelometer are the same as a light spectrophotometer except that the detector is placed at a specific angle from the incident light. Laboratory procedure manual centers for disease control. A lightemitting diode produces incident light at approximately 600 nm, and a photodetector detects variations in light scatter at. A nephelometer is an instrument for measuring the concentration of suspended particulates in. When light is passed through the suspension, part of incident radiant energy is dissipated by absorption, reflection, and reaction while remainder is transmitted.
