“Equivalent Sphere” Attitude

These diameters are fundamentally different for the same particle.The equivalent sphere diameters differ for any non-spherical material.Every PSA technique yields different results for non-spherical particles.

Slide 6/43

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.

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 particlesare stationary, thus will not effect particle size measurement.

No requirements for particles pre-knowledge of:1. Refractive index2. Temperature3. Viscosity variation4. Electrical conductivity5. Etc…

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. FDA 21 CFR Part 11 S/W security compliance.

information

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)
