DIPA-2000 Measuring Channels

Single Instrument ; Dual Measurement Channels

Slide 3/30

DIPA-2000 Laser Channel

Main Advantages:

Quick & Straight Forward Measurement

High Resolution Detection Capabilities

Time Domain Analysis, No “Pre-Knowledge”

Slide 4/30

The rotating laser beam scans single particles within its focus.

The diameter of the particle is directly correlated to the duration of the obscuration.

The measurement principle is a time interval, not an intensity measurement.

The time domain is independent of particles optical or physical properties.

Slide 5/30

From the duration of the obscuration (T),

and the known rotation velocity of the laser beam (V),

the particle diameter (D)

can be calculated:

D = V · TIn relation to the high speed of the laser rotating laser, the particles

are stationary, thus will not effect particle size measurement.

No requirements for particles pre-knowledge of:

1. Refractive index

2. Temperature

3. Viscosity variation

4. Electrical conductivity

5. Etc…

DIPA-2000 Laser Channel

Slide 6/30

Data is collected directly on each analyzed particle.

Detection of minor fractions, high resolution.

Correct measurement of particle size, not influenced by physical or optical properties.

Operation in Liquid, Dry and Aerosol mediums.

No calibration/alignment required by user.

Robust measurement, on-line indication for statistical significance.

Concentration measurement.

DIPA-2000 Video Channel

Main Advantages:

Sample Visualization

Dynamic Shape Analysis

Advanced Particles Size and Shape information

Slide 8/30

Dynamic Shape Analysis(DSA) Principle of Operation

Real time images of particles in motionare collected

Images are converted into a grid containing a collection of picture elements (pixels)

Each individual pixel has a value for brightness (grey level): 0 = Dark; 255 = White

All images are analyzed according to apre-defined set of Image Analysis characteristics

Measurement is finished when the analysis end conditions are met (# of particles/images, confidence level, time, etc)

DIPA-2000 Video Channel

Slide 10/30

• For each individual particle, all size and shape parameters are determined.

• The DIPA-2000 Image Analysis S/W automates set-up and measurement.

• DIPA-2000 IA software includes many procedures such as:

– Pre-Processing Procedures– Image Quality Filters– Region of Interest Determination– Out-Of-Focus Rejection– Morphology Operations– Grouping according to size/shape– Re-Processing of stored images and

movies– Manual Lens Calibration (Microscopy)

Slide 11/30

Image quality can be improved using automatic pre-processing procedures, such as “Contrast Enhancement”

Contrast Enhancement increases the number of gray levels
