Each participant will receive a comprehensive course manual consisting of printed notes and hard copies of the graphics used. The course manual will also include the following software, on a CD ROM disk:
Instruction in the use and application of these programs will be given during the course.
Course fee for an open course: 1250 GBP (No VAT), to include the manual, software, lunches, coffees/teas and course dinner (refer to methods of payment for details).
Existing techniques for particle size measurement will be reviewed, described and recommended, and recent developments will also be discussed. The course, however, is not intended to cover all possible methods of particle size measurement but only the most relevant and modern ones. Prominent attention, right at the beginning of the course, is given to the importance and application of sampling which is considered to be an integral and vital part of particle size measurement.
The course also deals with fundamental aspects of particle size measurement such as the underlying statistics, the practical evaluation and significance of the various definitions of mean particle size, and the application of the SPC techniques to statistical measurement control.
The course is intended for practicing particle size analysts or anybody else involved in particle technology, and is aimed at providing participants with an understanding of basic principles and the application of these principles to real problems. The course is equally useful to people dealing with dry powders as to those dealing with liquid suspensions, emulsions, pastes or with particulates suspended in gases such as aerosols or dusts.
Previous experience in particulate systems is helpful but not necessary. The emphasis is on practical applications and practical problems. All the lecturers are actively engaged in research and consultancy in particle technology and the lectures and course manual incorporate the results of recent experience and research.
The lectures will be supplemented by demonstration of equipment and methods, and by practical sessions. To-date, we have made arrangements for demonstrating a photo-sedimentometer, a spinning riffler, a sampling thief, a Coulter-Counter, a low angle laser light scattering instrument and some image analyser software.
Modern teaching methods and computer graphics will be used by the tutors in order to achieve maximum efficiency of learning in the time available.
The course is to be given by Professor Svarovsky with a group of visiting speakers, all internationally established authorities on the subject. The course has been given in various forms annually in Bradford (and, more recently, in Bexhill) since the sixties and occasionally abroad, also as an in-house course in many companies worldwide. This version is revised and updated, and even more industrially oriented than the previous offerings.
