Product Description

Principle

CCD camera with inversed microscope for particle size and shape analysis, based upon statistical image data analysis for measurement of emulsions, suspensions and dry powders.

Sample preparation :

  • Liquid mode : sedimentation of powders dispersed in carried liquid,
  • Dry mode: deposition of the powder on a slide.

Fields of application

  • Control the particle aggregation state,
  • Measure simultaneously the particle size and shape on the same sample.

Method of measurement

The particles are measured by the acquisition of the statistical numerical images associated with inverted microscope and computed by “Expert Shape” software.

Optical system

  • Light source: halogen Bulb 6V-30W,
  • Detection system: CCD detectors of camera,
  • Inverted microscope with different magnifications,
  • Four objective lenses: EPlan, Achromat, LWD (Long Work Distance): x4, x10, x20, x40 in standard.

Camera type

  • Number of pixels: 768 x 576 – CCIR
  • Pixel size: 8.6 µm (H) x 8.3 µm (V)
  • Pixel size: 8.6 µm (H) x 8.3 µm (V)
  • Voltage: 12V – DC

Well plate holder

Mechanical adapter for optical sample cell in wet mode and slide for dry powder.
With low position coaxial controls.

Size measurement

 Powder dispersion in dry or wet mode:
Size range in standard and depending upon materials properties and dispersion condition optimized with CILAS Particle Size Analyzer:
1 µm → 300 µm.

Compatible with CILAS Particle Size Analyzer 1190, 1090, 990 and Ecosizer with a wet mode dispersion system configuration.

Resolution

Approximate resolution of pixel size with corresponding of objective lens:

Magnification X4 X10 X20 X40
Resolution µm/pixel ~3,8 ~1,5 ~0,9 ~0,45

Shape measurement
