Size methods light scattering

The optical properties of bottles are a matter of crystallinity affected by nucle-ation, depending on the content and size of light-scattering polymer solids. The purity of the raw materials and the cleanness of the reactors are prerequisites for satisfactory quality. Bottle polymer should display as little contaminations as possible. The detection of impurities is carried out by the same methods as mentioned above. Thorough filtration of the polymer is therefore mandatory. It should... [Pg.478]

Other measurements important to visual air quality are pollutant related, i.e., the size distribution, mass concentration, and number concentration of airborne particles and their chemical composition. From the size distribution, the Mie theory of light scattering can be used to calculate the scattering coefficient (20). Table 14-2 summarizes the different types of visual monitoring methods (21). [Pg.209]
