Modular Laser Diffraction Analysis with the LS 13 320 XR

The LS 13 320 XR is the most advanced laser diffraction particle analyser on the market, operating with full implementation of the Fraunhofer and Mie theories of light scattering. This provides reliable quantification and characterisation of particles on the sub-micron scale, with a potential dynamic sizing range of 0.01 ? 2,000 micrometres (?m). Alternative technologies rely on estimations for particle size distributions in the micron scale, but the LS 13 320 XR provides real measurements through Polarisation Intensity Differential Scattering (PIDS) technology. This measures the differential intensity between three wavelengths of polarised light prior to integration into the Mie theory. This leading technological arrangement is supported by advanced modularity to provide unmatched levels of measurement specificity for distinct sample types. Dry powder samples and heterogeneous liquids comprising non-aqueous or aqueous solvents can be measured across the full dynamic range of the instrument, using two distinct sample chambers. In this blog post, we will explore the two modules of the LS 13 320 XR laser diffraction analyser in more detail. Universal Liquid Module The Universal Liquid Module (ULM) is a fully-automatic system designed for high-throughput analysis of organic liquid and aqueous samples of comparatively small volumes (>125ml). This provides maximum versatility with regards to diluent capacities, enabling laser diffraction analysis of samples as varied as seawater, pollutive waste, and synthetic solutions. Full control of sample dispersion is ensured by a variable speed pump which can maintain the consistency of emulsions comprising low to high levels of particulate density. It is also available with a sonicator option, which ensures uniform particle distribution throughout the liquid phase, eliminating measurement inaccuracies caused by sedimentation or agglomeration. The ULM is suitable for particle characterisation of various suspensions and complex emulsions. Tornado Dry Powder System The Tornado Dry Powder System (DPS) is a proprietary module for dry sample analysis. It was designed for easy sample loading into the optical bench of the LS 13 320 XR, with rapid subsequent measurements of dry powder samples across the entire particle size range of the instrument. Suitable sample types include synthetic polymers, geological sediments, raw construction materials such as cement or clinker, and many more. This is a high-automation system that reduces the need for operator intervention, with a completely hands-free operation via an intuitive software interface which supports automatic feed rate control.
