Light Scattering: LB-550 Dynamic Light Scattering Nano-Particle Size Analyzer

The LB-550 measures particle size from 1nm to 6µm and a concentration range from ppm up to 40% solids, all in as little as 30 seconds, making it ideally suited to a wide range of applications. Unlike traditional PCS-type instruments, most samples can be measured without dilution which can affect dispersion conditions and cause agglomeration.

With a standard analysis time of one to two minutes, the LB-550 is the fastest and most flexible particle size analyzer for the nanometer range of sizes. The Fourier-Transform/Iterative Deconvolution technique provides accurate results not only for average particle size, but also for distribution shape and identification of multiple modes, all without operator selections, a feature not found in most Photon Correlation Spectroscopy (PCS) instruments. Elimination of the need to select from alternative models and evaluating fitting errors provides confidence in the results and faster data analysis.

The temperature-controlled cell holder has a range of 5-70 degrees C for samples where size may change with temperature. Standard removable glass or disposable plastic curvettes are used to eliminate sample cross-contamination, ease cleaning and improve usability. Cells are available for sample volumes from 0.1-15ml. For high concentration samples where viscosity may affect results, a built-in viscometer option is available to provide accurate measurements at the time of analysis.
