Gravity Separation & Particle Analyser LUMiReader X-Ray 440

LUM GmbH – World Leader in Stability and Particle Analysis

LUM GmbH, based in Berlin, is one of the world's leading manufacturers of analytical systems for the direct and accelerated characterization of dispersions, emulsions, and suspensions.

LUMiReader® X-Ray 440 – X-ray Analysis for Your Most Demanding Materials

The LUMiReader® X-Ray 440 is a gravity-based particle and dispersion analyzer that combines the patented STEP‑Technology® (Space‑ and Time‑resolved Extinction Profiles) with monoenergetic X‑rays for the first time. This enables characterization of systems impenetrable to visible or near‑infrared light.

A microfocal X‑ray source with crystal optics generates parallel, monochromatic line radiation (17.48 keV) that illuminates the entire sample height (20 mm). A high‑resolution line detector records the transmitted radiation with micrometric spatial resolution. Transmission profiles are converted into X‑ray attenuation (ln I/I₀), providing volume concentrations, concentration gradients, separation kinetics, and packing densities.

Analysis is performed in‑situ, real‑time, non‑invasive, and non‑destructive – without dilution, independent of particle shape, size, or concentration (0.015–75 vol%).

Particle Sizing according to ISO 13317‑3

For the first time, the LUMiReader® X‑Ray enables X‑ray‑based particle sizing – even in opaque, highly concentrated samples. The measuring range covers 70 nm to 100 μm, and volume‑weighted distributions are determined without refractive index.
