Knowing what the sediment is made of can tell researchers a lot about where it came from, how it was transported, and what kind of chemical environment it has been in. Current Company Portfolio Beckman Coulter Life Sciences offers counters and particle analyzers that can be used for thousands of different applications working with suspensions, emulsions, or powders. The primary limitation of the Beckman Coulter machine is that it cannot distinguish between organic and rock-derived particles. (Determination of particle size distributions). Based on this principle, a layer with a high percentage of sand in an otherwise silty area indicates a storm event in a normally calm area, while a whole region of larger grains could indicate a beach with large waves or a strong current. Multiwavelength Particle Size Analyzer incorporates PIDS to provide measurements ranging from 0.017 m to 2,000 m. Larger particles are heavier and take more energy to transport, meaning high winds or fast moving water. Knowing the relative amounts of sand, silt, and clay in the sediment can be useful in a wide range of applications. By passing a sample through a laser beam and measuring the diffraction (bending of light), the device can tell us what percent of the sediment is of what grain size. The LS 13 320 XR is a particle sizing laser diffraction analyzer that distributes particles between 10 nm 3,500 µm. Complex sample analysis across wide particle size distribution range.
