LUMiReader® X-Ray – Illuminating even the most concentrated samples

Maximum comparison precision and no material data such as viscosity or density required

The LUMiReader® X-Ray is a gravity particle and dispersion analyser: to study dispersability, stability, separation, and consolidation phenomena for completely
transparent to completely opaque emulsions or suspensions. For the first time, X-rays illuminate your sample instantaneously from top to bottom. Solve your most challenging inorganic material problems with complete insight.

Go places light cannot.
Our patented solution combines X-ray vision with the proven STEP-Technology®, permitting highest spatial resolution, short sampling intervals and powerful
detection technique. The LUMiReader® X-Ray creates monochrome and parallel X-rays with the help of a special crystal, which transmits the entire sample cell of 20 mm height.


The X-ray line detector records the transmitted beam, giving an unprecedented resolution. Instantaneous transmission profiles across your whole sample are converted into stability and separation rates. Particle concentration, sediment packing density can also be calculated based on the extinction profiles. The obtained Space- and Time-resolved Extinction Profiles across your whole sample are converted into concentration gradients as well as stability and separation rates. Particle size distribution, particle density, volume concentration and sediment packing density can also be calculated based on the extinction profiles 4 - 7 .

The LUMiReader® X-Ray allows you to characterize and optimize particle, formulation and product properties, from dispersibility via stability & separation to the quantification of separated phases and solid matrices. Regardless of the shape or concentration of your dispersed particles and droplets. In-situ, real-time, non-invasive and non-destructive.
Typical applications are cosmetics, pharmaceutics, paint & pigments, construction materials and fillers, as well as mining, ceramics and petrol industry dealing with complex emulsions, slurries and sludges.

There are many claims out there about the ability to analyze concentrated systems. When pressed however, it turns out that what is concentrated to one person is dilute to another. With that in mind, and wanting to avoid any confusion, all we can state unequivocally is that the LUMiReader X-Ray was designed with one goal in mind: to allow you to analyze and understand concentrated and totally opaque emulsions and suspensions.

How concentrated? As high as you want to go. As opaque as you want it to be. Top to bottom, instantaneously. No other technology can do this. Not even close.

The LUMiReader X-Ray is simple to operate. It comes certified, factory pre-calibrated and ready-to-go.

Advanced Particle Sizing with the LUMiReader® X-Ray

X-ray extinction for particle sizing beyond optical limits

Particle sizing of inorganic materials with the LUMiReader® X-Ray (LRX), all advantages of separating techniques apply, is based on monochrome X-ray transmission, providing a
powerful alternative to optical methods that struggle with opaque or highly concentrated dispersions. By applying Lambert-Beer’s law, the instrument translates X-ray attenuation
into direct information about the volume concentration of suspended particles, even in samples that are impenetrable to visible or near-infrared light.

Analysis of particle size distribution follows ISO 13317-3:2001 “Determination of particle size distribution by gravitational liquid sedimentation methods; Part 3: X-ray gravitational technique”. Display the raw data and apply several fit functions.

 

 

ADVANTAGES OF PARTICLE SIZING WITH LRX

1. Particle and droplet sizing over whole sample (STEP).
2. True raw data – direct physical measurement.
3. From nm to µm same principle.
4. Multimodal systems with high resolution.
5. Higher concentrations than other techniques.
6. No restrictions regarding liquid continuous phase (closed cell).
7. No refractive indices required for volume-weighted particle size distribution.
