3 Slide 3/30 DIPA-2000 Measuring Channels Single Instrument ; Dual Measurement Channels

4 DIPA-2000 Laser Channel Slide 4/30 Main Advantages: Quick & Straight Forward Measurement High Resolution Detection Capabilities Time Domain Analysis, No Pre-Knowledge

5 DIPA-2000 Laser Channel Slide 5/30 Scanning Laser V A B C D E F T a T b T c T d T e T f Time 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.

6 Slide 6/30 DIPA-2000 Laser Channel 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 T In 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

7 DIPA-2000 Laser Channel Summery Slide 7/30 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. FDA 21 CFR Part 11 S/W security compliance.

8 DIPA-2000 Video Channel Slide 8/30 Main Advantages: Sample Visualization Dynamic Shape Analysis Advanced Particles Size and Shape information

9 Dynamic Shape Analysis (DSA) Principle of Operation Slide 9/30 Real time images of particles in motion are 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 420 µm Image Conversion All images are analyzed according to a pre-defined set of Image Analysis characteristics Measurement is finished when the analysis end conditions are met (# of particles/images, confidence level, time, etc) 18 µm

10 DIPA-2000 Video Channel Slide 10/30 DIPA-2000 DSA Main Features: Easy setup and measurement using software wizards Advanced pre-processing algorithms Size and Shape Filter/Grouping Automated Report Generation Storage of real raw date (un-processed images) Re-processing of raw data Internal optical calibration and verification tools available Interface with 3 rd party hardware (Microscopy)

11 DIPA-2000 Video Channel Slide 11/30 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)

12 DIPA-2000 Video Channel Pre-Processing Slide 12/30 Image quality can be improved using automatic preprocessing procedures, such as Contrast Enhancement Contrast Enhancement increases the number of gray levels

13 Slide 13/30 DIPA-2000 Video Channel Grouping / Shape Filters Shape Filters can be set up to analyze a specific group of particles based on size and/or shape characterization Some Known Applications: Fiber Analysis Shape of Sieve Fraction Abrasives Oil-In-Water Minor fraction in Matrix And many more All Particles: Shape Filter Shape Factor < 0,8: Average Size of non-spherical particles in sample

14 DIPA-2000 Video Channel Object Data-Base Slide 14/30 The complete shape information for every particle is saved in the object data base. For each Particle all data analysis results can be viewed individually.

15 DIPA-2000 Video Channel Summery Slide 15/30 Seeing is believing, visualize your sampled particles. Better and advanced characterization of materials. High resolution data (down to pixel size data). Detection and quantification of shape parameters. Validation technique for the Laser Channel or other particle size methods. Detection capability of minor fractions for fine particles or agglomerated materials. Quantification of material homogenity. Advanced tool for shape differences characterisation. FDA 21 CFR Part 11 S/W security compliance.
