Since the initial introduction of laser diffraction instrumentation in the 1970s, many different applications to panicle si/e aniilysis have been reported. Ihese have included measurements of si/e distributions of radioactive tracer particles, ink particles used in photocopy machines, zirconia fibers, alumina particles, droplets from electronic fuel injectors, crystal growth particles, coal powders, cosmetics, soils, resins, pharmaceuticals, metal catalysts, electronic materials, phoiugraphic emulsions, organic pigments, and ceramics. About a dozen instrument companies now produce LALLS instruments. Some I.AI.LS instruments have become popular as detectors for size-exclusion chromatography. 

The latter methods were almost fully substituted with size exclusion chromatography, though especially light scattering and viscometry are often used for detection in SEC (see section 11.7.3.2, Mobile Phases and Detectors for Size Exclusion Chromatography). 

Thus calibration of the apparatus with, for example, polystyrene standards with known values of K and a in the particular solvent at a particular temperature permits the absolute molecular mass to be calculated via the universal calibration method [9]. A further advantage of the detector is its ability to be used at temperatures up to 150°C, thus permitting the analysis of polyolefins. The study of branching in polymers is also possible with this system. This new detector probably represents the most significant advance in detectors for size exclusion chromatography in recent years.
