The trips last winter were fast and furious. With one daughter traveling with her high school show choir and another daughter traveling with her college gymnastics team, you and your husband had to divide and conquer. One of you would stay in town for the show choir competitions that were within driving distance, while the other would board a plane heading for the gymnastics meets that were throughout the country. Between hotel reservations and airline flights, it was an expensive view months.
Americans are not known for the decisions to stay at home and let moss grow around their feet. From summer family vacations to trips for work, many families spend several nights a year in motels and bed and breakfast accommodations around the country. And while many of these stays can be fairly expensive, th
Traditionally, particle size analysis was conducted using sieving and sedimentation. Over the past 2 decades, however, laser diffraction has significantly replaced these traditional methods.
Particle Sizing and Sieving
This method for providing an analysis of particle size is the oldest in use. It continues to be used, however, for measuring relatively large particles of approximately 1 millimeter.
Particle Sizing and Laser Diffraction Analysis
This method of sizing is especially used for particles that range in size from 0.5 to 1000 microns. Basically, when a laser’s light beam is scattered by a group of particles, the angle at which it scatters is inversely proportional to the size of the particle. In other words, the smaller the particle, the larger the an
