1. nephelometry

   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 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. There are a wide variety of research-grade nephelometers on the market as well as open source varieties.

1. Nephelometry

   Nephelometry is a technique used in immunology to determine the levels of several blood plasma proteins. For example the total levels of antibodies isotypes or classes: Immunoglobulin M, Immunoglobulin G, and Immunoglobulin A. It is important in quantification of M-proteins in diseases such as multiple myeloma. Quantification is important for disease classification and for disease monitoring once a patient has been treated. It is performed by measuring the turbidity in a water sample by passing light through the sample being measured. In nephelometry the measurement is made by measuring the light passed through a sample at an angle. This technique is widely used in clinical laboratories because it is relatively easily automated. It is based on the principle that a dilute suspension of small particles will scatter light passed through it rather than simply absorbing it. The amount of scatter is determined by collecting the light at an angle. Antibody and the antigen are mixed in concentrations such that only small aggregates are formed that do not quickly settle to the bottom. The amount of light scatter is measured and compared to the amount of scatter from known mixtures. The amount of the unknown is determined from a standard curve.
