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.

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.
