It may be recalculated in terms of clarification and particle concentration. Each LUMiReader contains an optical block and temperature control element. In addition, the specially designed PSA module also opens new horizons for high resolution particle sizing and allows you to measure the velocity distribution of separating particles. There is no need for you to know any material constants such as viscosity or density. Our proprietary design ensures that the light strikes the sample across its entire height, ensuring maximum optical sensitivity and reproducibility. The optical detector assembly features micro-scale spatial resolution capable of accurately measuring even the smallest local changes instantaneously across the entire sample height. This design eliminates the time-consuming and less accurate task of scanning your sample, allowing you to capture even very fast micro-changes occuring in your dispersion without mechanical vibration. The LUMiReader also uses a patented tilt technology based on the Boycott effect. The well-known principle allows accelerated, real-time stability testing at gravity by tilting the sample from its normal upright position. The magnitude of acceleration (up to 10 times) depends on geometric factors, such as tilt angle, vial dimensions, and sample type. Analyse in a wide range of viscosities, temperatures, and concentrations. With the advantage of looking at the entire sample from top to bottom instantaneously, you can observe and understand different stability/instability phenomena concurrently; for example, creaming, sedimentation coalescence, aggregation and flocculation at original product concentration. Comes with state-of-the-art software SEPView. The LUMiReader comes certified, factory pre-calibrated and is ready-to-go. International norms and guidelines THE LUMiReader® PSA MEETS THE FOLLOWING STANDARDS ASTM D7827 CFR 21 Part 11 ISO 13317-1 ISO 13317-5 ISO 18747-1 ISO 20427 ISO/TR 13097 MATERIAL OVERVIEW The following materials can be analyzed with the LUMiReader® PSA Abrasives Asphaltenes Carbon black Ceramics Crude oil Fine chemicals Food Gas oil Ink Petrol Pharmaceutical dispersions Polymers Sludges Slurries and many more materials. MULTI-WAVELENGTHS Determination of the volume-weighted particle size distribution The LUMiReader PSA allows for the first time the determination of the volume based particle size distribution (ISO 13317) for emulsions and suspensions, without the necessity of knowing the refractive index or software input and no assumption regarding particle shape and shape distribution. This opens new horizons for the characterization of industrial products, where above parameters are often not available or not applicable. LUM’s patented STEP-Technology, the measurement of Space and Time-resolved Extinction Profiles, was extended to an unique new multi-wavelength approach: alterations of ratio of transmission at different wavelengths monitors any particle or droplet size variation over product life without sizing particles itself. Giving particle size distribution (ISO 13317), separation velocity distribution and hydrodynamic particle density in addition to the direct stability result according to ISO TR 13097, the new LUMiReader PSA is one instrument for the comprehensive understanding of complex industrial products in an easy way.
