The application of an OPC or Nephelometer depends on the measured environment and any regulatory requirements. OPC’s are required for measurements in cleanrooms or where the required measurements are in particles per liter.

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 free light chains in diseases such as multiple myeloma. Quantification is important for disease classification and for disease monitoring once a patient has been treated (increased skewing of the ratio between kap… WebDesign Features.
