LS 13 320 XR Laser Diffraction Analyzer Features


Expanded measurement range for a wider array of particle analysis

The expanded dynamic measurement range provides real (not extrapolated) analytical data down to 10 nm, and high-resolution measurements up to 3,000 μm.


Enhanced Polarization Intensity Differential Scattering (PIDS) technology:

PIDS technology enables more precise raw data detection and increased detector sensitivity of vertical and horizontal polarized scattered light for sub-μm particle size analysis—a measurement quality previously unavailable.

The intensity vs. scattering angle information from PIDS signals is incorporated into the standard algorithm from the intensity vs. scattering angle data from laser light scattering to give a continuous size distribution.

Another major benefit of acquiring PIDS data is that simple interpretation of raw data can quickly confirm if small particles are actually present, as large particles don’t exhibit the differential signal shown by small particles.

Advanced automodality

No knowledge about particle size distribution (e.g., multiple fractions, narrow distribution) needed prior to measurement in order to obtain a correct result.


Easy-to-use software helps compress workflows, expedite method creation, and simplify daily operation by experienced/inexperienced users alike

For time savings during operating hours in QC or R&D laboratories, LS 13 320 XR software enables customized SOM creation. You need only define module settings, sample properties (including definition of the sampled material) and the carrier fluid.

After a method is saved, it can be used 24/7 for all measurements without creating a new method. And as soon as a method is programmed into LS 13 320 XR software, a measurement can be started with 3 clicks:

  1. Choose a pre-configured method
  2. Define Test-ID and Group-ID
  3. Click Start Measurement

Your results will appear in < 60 seconds.
