　　Beckman Coulter Extends Range of LS 13 320 Particle Size Analysis System Instrument Characterizes Particles as Small as 17 Nanometers

　　BREA, Calif. (March 1, 2010) – Beckman Coulter, Inc., has extended the range of its industry leading LS 13 320particle size analyzer to allow high-resolution, reproducible measurement of samples from .017 to 2000 μm. Theenhanced LS 13 320 also adds Rosin-Rammler and Folk & Ward Phi methods to its full complement of standardanalytical capabilities.

　　The instrument s patented Tornado Dry Powder Dispersing System keeps sample particles intact, allowing truemeasurement of the original samples. Reproducibility is typically better than one percent. These features combine with the extended size range to provide high-accuracy/highresolution detection without the risk of missing either the largest or the smallest particles in a sample The LS 13 320 differs from other laser-based instruments by virtue of its wide dynamic size range, number of detectors and sample measurement options. Reverse Fourier optics incorporated in a patented fiber-optic spatial filter system optimize light scattering measurement. Polarization Intensity Differential Scattering (PIDS) technology, a Beckman Coulter exclusive, furthers detection capabilities in pharmaceutical, plastics, food and beverage, and a variety of other applications.

　　"The expanded analytical range of the LS 13 320 will provide our customers with the ability to more accurately monitor and control their samples and processes," said Elsa Burgess, director, Beckman Coulter Particle Characterization Business Center. "We are committed to the continuous evolution of these instruments and to bringing new levels of accuracy and ease-of-use to particle characterization.
