Available in PDF, EPUB and Kindle. Book excerpt: In recent decades oil analysis laboratories have used automatic particle counters to determine the number and size of particles in many oil wetted systems. Once determined, there has been the question of "what are they?" Logically, the next step is to investigate the make-up of the particles by extracting the particles and analyzing using emission spectroscopy and/or a filter membrane for view them under magnification. Characterizing the make-up of the particles is very useful in determining the source. A cost-effective action plan can be undertaken to rectify the identified problem once the particle type is determined. The problem with these two approaches is; emission spectroscopy analysis is often unreliable in identifying larger particles and; under optical magnification it is not possible to tell for sure the makeup of the particles. In some cases scanning electron microscopy (SEM) analysis is undertaken to further identify the particles. This proves to be time-consuming for the SEM operator and is left to the operator to judge which areas of the sample to investigate. This study illustrates the performance and innovative approach to resolving the aforementioned limitations on sizing and identifying particles using an "Automated Electron Beam Particle Analyzer" equipped with "Automated Feature Analysis" (AFA) software to characterize complex matrix of particles extracted onto a membrane filter from oil samples.

Download or read book Particle Size Analysis written by N G Stanley-Wood and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Particle Size Measurements written by Henk G. Merkus and published by Springer Science & Business Media. This book was released on 2009-01-07 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Although man's environment, from the interstellar dust to the earth beneath his feet, is composed to a large extent of finely divided material, his knowledge of the propert ies of such materials is surprisingly slight. For many years the scientist has accepted that matter may exist as solids, liquids or gases although the dividing line between the states may often be rather blurred; this classification has been upset by powders, which at rest are solids, when aerated may behave as liquids, and when suspended in gases take on some of the properties of gases. It is now widely recognized that powder technology is a field of study in its own right. The industrial applications of this new science are far reaching. The size of fine particles affects the properties of a powder in many important ways. For example, it determines the setting time of cement, the hiding power of pigments and the activity of chemical catalysts; the taste of food, the potency of drugs and the sintering shrink age of metallurgical powders are also strongly affected by the size of the particles of which the powder is made up. Particle size measurement is to powder technology as thermometry is to the study of heat and is in the same state of flux as thermometry was in its early days. Only in the case of a sphere can the size of a particle be completely described by one number.

Available in PDF, EPUB and Kindle. Book excerpt: Work was performed to develop a prototype Particle Size Analyzer (PSA) for application to coated particle fuel characterization. This system was based on a light obscuration method and targeted towards high throughput analysis. Although never matured to the point of replacing existing lower throughput optical microscopy shadowgraph methods, the system was successfully applied to automating the counting of large particle samples for increased accuracy in calculating mean particle properties based on measurements of multiparticle samples. The measurement of particle size with the PSA was compared to current shadowgraph techniques and found to result in considerably greater throughput at the cost of larger measurement uncertainty. The current algorithm used by the PSA is more sensitive to particle shape and this is a likely cause of the greater uncertainty when attempting to measure average particle diameter. The use of the PSA to measure particle shape will require further development. Particle transport through the PSA and stability of the light source/detector are key elements in the successful application of this technique. A number of system pitfalls were studied and addressed.

Available in PDF, EPUB and Kindle. Book excerpt: Powder technology is a rapidly expanding technology and nowhere more than in particle characterization. There has been an explosion of new particle measuring techniques in the past ten year particularly in the field of on-line measurement. One of the main aims of this book is to bring the reader up-to-date with current practices. One important area of interest is the improvements in on-line light scattering instruments and the introduction of ultrasonic on-line devices. Another is the introduction of on-line microscopy, which permits shape analysis in conjunction with particle sizing.Schools of powder technology are common in Europe and Japan but the importance of this subject has only recently been recognised in America with the emergence of the Particle Research Centre (PERC) at the University of Florida in Gainsville. - Details all the latest developments in powder technology - Written by established authority on powder technology- A comprehensive text covering all aspects of powder technology and handling of particulate solids including characterization, handling and applications

Available in PDF, EPUB and Kindle. Book excerpt: While the hydrometer method (ASTM 422-63) has proven to be an accurate method of particle-size analysis of soil and is relatively inexpensive to conduct, it is prone to operator error as well as taking a minimum of 24 hours to conduct. Recent research has shown that an automated X-ray absorption instrument can closely approximate hydrometer test results for soils. The X-ray absorption instrument determines the change in mass of a sedimenting soil-water suspension through the absoiption of X-rays while utilizing Stokes' law to determine particle sizes in the range from 300 ?m to 0.1 ?m. A number of hydrometer tests on three different soils were conducted and compared with particle-size analysis using an X-ray absorption instrument. Controlled testing between the hydrometer and the X-ray absoiption instrument produced almost identical results for silts while tests on clay show good agreement from 75 ?m through about 10 ?m. However, below 10 ?m the X-ray absorption test results start to show a slightly higher percent of fines than the hydrometer test, with the percent difference increasing as the particle size decreases. The increase appears to be related to the plasticity of the clay, with low plasticity clay showing an average increase of only 1 to 3 percent, while the higher plasticity clays vary from an average of 3 to 6 percent.
