"Nephelometry offers a means of determining directly the mass or weight of precipitate in suspension, without filtering, washing, drying, and weighing. The method is based upon the measurement of the brightness of the light reflected by finely divided particles in suspension, very much as in an ultramicroscope. The intensity of the reflected light is a function of the amount of suspended particles, other conditions being kept constant". ; Ex-Library; 8vo - over 7¾" - 9¾" tall; 337 pages
