Particle Size Analysis In Pharmaceutics And Other Industries Theory And Practice

Recent major advances in particle size analysis, particularly with regard to its application in the pharmaceutical and related industries, provides justification for this title. It is a book for technicians and senior technicians, project and development managers, and formulation More...development scientists in a wide range of industries, pharmace

Particle Size Analysis reviews the development of particle characterization over the past 25 years and also speculates on its future. Interest in the subject has increased enormously over the years and this book highlights the changes and advances made within the field. This book is comprehensive in its coverage of particle size analysis and includes contributions on such characterization techniques as microscopy using fractal analysis, light diffraction, light scattering with the phase doppler technique, light observation, and photon correlation spectroscopy. A number of chapters address the interest in on-line in-stream particle size analysis and illustrate the progress being made in achieving this long sought after ideal of in-situ in-process particle characterization. Applications to other technological fields are detailed by chapters covering biological systems and the pharmaceutical industry. The subject of surface area determination is considered with particular emphasis on the measurements on porosity of powders, the characterization and comparability of reference materials, and the need for standards. Particle Size Analysis should provide stimulating reading for technologists, scientists, and engineers involved in particle characterization and powder technology worldwide.

At Particle Analytical, we have been working with determination of particle sizes for the pharmaceutical industry since 2000. Our customers have in general showed a large interest for an introduction to this area from a down-to-earth and practical perspective. The intended readers of this booklet are pharmacists and technicians working with determination of particles sizes. This booklet is not meant as a thorough introduction into theory behind determination of particle sizes, and only a limited number of references will be given: The booklet is primarily based on our own experiences and is a practical introduction to the area with a brief introduction to "why" and "how" in determination of particle sizes.

This book focuses on the practical aspects of particle size measurement: a major difference with existing books, which have a more theoretical approach. Of course, the emphasis still lies on the measurement techniques. For optimum application, their theoretical background is accompanied by quantitative quality aspects, limitations and problem identification. In addition the book covers the phenomena of sampling and dispersion of powders, either of which may be dominant in the overall analysis error. Moreover, there are chapters on the general aspects of quality for particle size analysis, quality management, reference materials and written standards, in- and on-line measurement, definitions and multilingual terminology, and on the statistics required for adequate interpretation of results. Importantly, a relation is made to product performance, both during processing as well as in final application. In view of its set-up, this book is well suited to support particle size measurement courses.

The use of analytical sciences in the discovery, development andmanufacture of pharmaceuticals is wide-ranging. From the analysisof minute amounts of complex biological materials to the qualitycontrol of the final dosage form, the use of analytical technologycovers an immense range of techniques and disciplines. This book concentrates on the analytical aspects of drugdevelopment and manufacture, focusing on the analysis of the activeingredient or drug substance. It provides those joining theindustry or other areas of pharmaceutical research with a source ofreference to a broad range of techniques and their applications,allowing them to choose the most appropriate analytical techniquefor a particular purpose. The volume is directed at analytical chemists, industrialpharmacists, organic chemists, pharmaceutical chemists andbiochemists.

There has been a rapid evolution in the field of inhalation drug therapy, including new drugs, increased regulation and quality control, and strong pressure from generics. Inhalation Drug Therapy brings together the most current inhalation drug research, as well as practical developments and processes, into one essential guide. Focusing on inhalation products and specific equipment and techniques used in manufacturing and quality control, the book balances research with the industrial aspects of creating the drugs, and features a highly regarded author team with both academic and industry experience.

This unique reference integrates the theory and practical use of aerosols in inhalation therapy into a single resource-presenting the physical chemistry of formulation, the physics of aerosol generation, aerodynamic behavior, and therapeutic implications. Offers up-to-date techniques for droplet and particle generation, including air-blast and ultrasonic nebulizers, propellant-driven metered-dose inhalers, dry-powder inhalers, and elecctrospray systems!
