Dynamic Image Analysis is a perfect method if not only the particle size of powders is to be determined, but if you also want to ascertain something about their shape. For this purpose the FRITSCH GmbH provides with the Particle Sizer ANALYSETTE 28 ImageSizer a functional, economically priced instrument, which is utilized for dry, well free flowing bulk solids.
Laser diffraction - for quick and dependable determination of the particle size. Areas of application cover practically all branches of industry. For example, laser diffraction can be found in the receiving, but also in the pre-delivery inspection of base materials, in which their particle size is significant for the processability or for the quality and directly related end product. Or for the control of individual process steps, the size distribution of intermediate goods is determined.
The development of below sea level deposits offshore the west coast of the Antarctic Peninsula was influenced by the variation of the continental ice shield and the amount of ice in the ocean, which in turn influence the global climate. With core-depth drillings, these variations can be backtracked over periods of several million of years.
The ability of matter, to transmit light waves, is specified as transparency. If “something positioned behind something” can be relatively clearly recognizable, normally the material is considered transparent or lucent like in the case of window glass. This is the case for most gaseous, as well as many liquids substances and some solid materials.
The trait of effect metal varnishes is brilliance and luminance of the varnishing. Special significance above this has the Flip-Flop or two tone effect, which results from the alteration of the luminance sensation during modification of the viewing angle. This effect depends on the utilized metal pigment and its adjustment in the varnish film. The addition of certain additives fosters the mostly simply called “Flop” effect in metal effect varnishes. The dependency of the visual image of the metal effect varnishes is here substantially influenced by the used additive, respectively its particle diameter.
The sieve analysis is due to good reason no ICC- standard method, because it can not be standardized. Two steps are processed in trying to improve the reproducibility of a sieve analysis of flour. A better reproducibility is achieved with the Laser Particle Sizer.
Particle sizes of chocolate and chocolate products strongly influence the mouthfeel of the chocolate product — a very small particle size would produce a “smooth” sensation in the mouth. To achieve the desired quality not only the careful testing of final products, but also the monitoring of the production process is mandatory.
Procaine is a local anaesthetic - an ester type - which is used very seldom today as a local anaesthetic, since much more effective and more deeply penetrating substances like for example lidocaine are available, where allergic reactions are less occurring. However, procaine is still used in the neural therapy, a type of treatment from the areas of alternative or animal medicine.
The majority of all drugs have to - in order to unfold their full effectiveness - reach the bloodstream.

Microscopic small glass spheres can be used for a many of applications: in mechanical engineering as an abrasion deterring element in grating components, in micro electronic mechanics as an adjusting aid and distancing element of electricity conducting single components, as a material for artistic surface design and more.
