SEDITEST

 

SediTest

  • Monomodal particle suspensions
  • Reference material for particle size and sedimentation analysis
  • ready to use
  • with certificate of analysis

 

Properties

SediTest - Particle suspensions in the size range 100 nm - 1000 nm:

  • Spherical silica microparticles with excellent dimensional stability and narrow size dispersion for use as sedimentation and particle size standard for optical sedimentation analyzers (e.g. LUMiFuge®, LUMiSizer®)
  • Monomodal suspensions with the nominal particle diameters: 170 nm, 250 nm, 550 nm and 1000 nm are available.

Particle size distributions of submicron silica particles, 
Sedimentation analysis using LUMiSizer® (2 mm cells, λ=470 nm, T=25°C, 500-4000 U/min)
 

SediTest - Particle suspensions in the size range 15 μm - 40 μm:

  • Spherical microparticles of cross-linked PMMA with excellent dimensional stability and narrow size dispersion for use as sedimentation and particle size standard for optical sedimentation analyzers (e.g. LUMiReader®)
  • There are monomodal suspensions with the nominal particle diameters: 15μm, 20μm, 29μm and 38μm available.

USAGE

 

The monomodal particle suspensions can be used advantageously for validation and qualification of high resolution particle sizers such as e.g. LUMiFuge®, LUMiSizer® or LUMiReader®-PSA  (LUM GmbH).  They cover a wide particle size range and, due to their defined size grading and particle size distribution, allow the user to test resolution and accuracy of the analytical method.

 

Of course, SediTest is also suitable for use in other devices.

 

The use of SediTest with LUMiSizer® or LUMiReader®-PSA doesn'nt require special sample preparation; the suspension only needs to be briefly redispersed. All required information can be found in the enclosed instructions for use.

 

SediTest-Particle suspensions are supplied with a particle size certificate.
