Wet dispersion: 0.02 to 2,600 μm; Dry dispersion: 0.1 to 2,600 μm; Dynamic imaging: 2.0 to 3,500 μm. Get A Quote Now.The LA-960 combines the most popular modern sizing technique with state of the art refinements to measure wet and dry samples measuring 10 nanometers to 5 millimeters. The central idea in laser diffraction is that a particle will scatter light at an angle determined by that particle’s size.
Moreover, the P method is also defined as a standard for measurement in mineral soils by the International Organization for Standardization (ISO 11277, 2009). Since sand particles, usually above 50 µm, are not measured with pipette and hydrometer, these methods are commonly coupled with dry and wet sieving for large size particles.
In this article, we will cover the advantages of laser diffraction, as well as the inevitable challenges it faces. We will also discuss the Mastersizer 3000, the world’s most popular particle sizing instrument, as the best solution for particle size analysis and identify a best practice sampling method. Advantages of laser diffractionThe Bettersizer 2600 is a powerful and versatile particle size analyzer for both wet and dry sample measurements. Based on its innovative optical system and standard operating procedure (SOP), the Bettersizer 2600 delivers precise particle size distributions from 0.02 to 2600 μm. In laser diffraction particle size analysis, inaccurate results can be caused by particle agglomerating in the suspension, especially when they are fine.Therefore, a full dispersion of the sample prior to measurement is essential. Three effective methods are available for the sample dispersion when using the wet method. Primary dispersion of aggregates can . Equally importantly, however, recent instruments have brought enhanced dry- powder dispersion capability. Relative to wet measurement, dry-laser diffraction particle-size analysis is faster and has a lower environmental footprint because no dispersants are required. Developments in this area, therefore, offer significant practical benefit.
Traditional methods for grain size analysis are generally based on sieving procedure for coarse fractions and sedimentation procedure for fine ones [1]. The different methods for particle size determination generally include direct measurement, dry and wet sieving, settling tube analysis, pipette and laser granulometer, X-ray Sedigraph
