Web1. SUMMARY OF TEST PRINCIPLE AND CLINICAL RELEVANCE This method quantifies C-reactive protein (CRP) by latex-enhanced nephelometry. Particle-enhanced assays … A nephelometer or aerosol photometer is an instrument for measuring the concentration of suspended particulates in a 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 som…

Scattering of light in liquids follows the rules of elastic scattering of particles, where no energy is absorbed by either particle during the “collision”. The energy of a photon before and after the scattering remains the same. Elastic scattering differs in large and small particles. For large particles, the light gets scattered in … See more The relativity of intensity of scattered light (IS) and the concentration of the precipitate (C) is: IS = kS * I0 * C where, kS is a constant I0 is the intensity of light. There are different … See more Wavelength selection is considered irrelevant because the incident light absorption by the suspended particles is generally not considered, and does not induce fluorescence of the sample.

When a light beam is incident on the particles, it is scattered and strikes photomultiplier devices placed at some angle to the beam path. This angle is usually 90 degrees but may also be 70 degrees or another angle at which the maximum scattering intensity is observed. rockstar dababy ft. roddy ricch
