摘要： The present invention provides methods for the use of visible and/or near-infrared spectroscopic methodology to monitor and control processes for the generation of particles, including processes that provide for a reduction in particle size and processes that result in an increase in particle size. One embodiment of the present invention employs visible and/or near-infrared diffuse reflectance spectroscopy to monitor particle size. The present invention is particularly useful for monitoring particle size of optically dense samples and is further useful for monitoring the endpoint of particle generation processes. In contrast to methods known in the art, the present invention is especially useful for on-line monitoring of particle size.

摘要： Multilayer film structures and packages therefrom which are particularly suited for containing organics such as organic liquids or solvents, e.g., amines, diamines, triamines, xylenes, tolene, ethoxyethanols, urethanes, or epoxies, or the like, or materials containing organics are disclosed as are methods for containing such organics. The film structures have two layer elements. The first layer element has a flexible barrier material layer and a sealant layer; the second layer element has a high barrier material layer; and when formed into a package such as a pouch the sealant layer is disposed interiorly and is used to seal the package together. Suitable materials for the high barrier material include metal foil, e.g., aluminum foil, and nylon coated on at least one side with a polyvinylidene chloride copolymer; the flexible barrier material layer is suitably nylon; and, the sealant is preferably ethylene vinyl acetate. Additional layers such as additional primer, adhesive, tie or sealant layers can also be present as can at least one protective layer disposed over the high barrier material layer. The packages of this invention can contain the organics in varying conditions, including elevated heat and/or humidity, without blistering, bubbling, cracking or product permeation.
