  • The chapter commences by reviewing the properties of the broad classes of materials used in film coating, polymers, plasticizers, pigments and solvents (or vehicles). An initial consideration of the polymers shows that while processing is most commonly performed using these materials in solution, there are systems which utilize polymers in suspension in water. The mechanism of coalescence and film formation for these types of materials are discussed.

  • Size-exclusion chromatography (SEC) separates polymer molecules and biomolecules based on differences in their molecular size. The separation process in simplified form is based on the ability of sample molecules to penetrate inside the pores of packing material and is dependent on the relative size of analyte molecules and the respective pore size of the absorbent. The process also relies on the absence of any interactions with the packing material surface. Two types of SEC are usually distinguished: 1.

  • Modified release coatings John E.Hogan SUMMARY Relevant aspects of the composition and performance of modified release coatings are considered in this chapter. Initially, the basic characteristics of multiparticulate systems are described and comparisons are made with the performance of whole tablets intended for modified release. The properties and effects of the polymers and plasticizers which are used in modified release coatings are illustrated with examples from the literature. This further develops the basic treatment of these materials provided in Chapter 2.

  • Although the technologies on chiral/enantiomer separation and stereoselective analysis have matured in the past ca. 20 years, the development of new, even more advanced chiral separation materials, mechanisms and methods still belong to the more challenging tasks in separation science and analytical chemistry. An analysis of recent trends indicates that capillary electrophoresis (CE) can show real advantages over chromatographic methods in ultratrace chiral determination of biologically active ionogenic compounds in complex matrices, including mostly biological ones....

  • Ionic methods of separation have been used since the industrial revolution in Europe to reduce hardness of water. In the mid-nineteenth century, British researchers treated various clays with ammonium sulfate or carbonate in solution to release calcium. In the early twentieth century, zeolite columns were used to remove interfering calcium and magnesium ions from solutions to permit determination of sulfate. Ionic separation procedures were used in the Manhattan project to purify and concentrate radioactive materials needed to make atom bombs.

  • The report also identifies water-related risks for electric power/energy, apparel, biotechnology/pharmaceutical, forest products and metals/mining firms. For companies in these and other sectors, climate change will further reduce the availability of reliable and high quality water, impacting productivity, costs, revenues, public goodwill and reputation. The report highlights the intensifying conflict between energy use and water availability. With increasing frequency, choosing one of these resources means undermining the other – the other, usually being water.

  • An inventory of all the chemicals including pharmaceuticals was made and a special task force was formed to advise the government on proper disposal system. Many donors were approached to provide financial assistance for the disposal but the response was until 1995 when the Netherlands government offered 1.5 million USD for the whole exercise which involved repacking, recollection in special centers and finally to remove the chemicals including pharmaceuticals to be incinerated in the UK. Rechem Company was contracted to do the job and 400 tons were removed in 1995.
