Powders, granulars, and liquids, can now be analyzed with extreme precision, using a number of innovative sample transport techniques. For less dense powders, vacuum dispersion, either by itself, or in conjunction with a vibrating platform, are utilized to move the particles in to the field of view. Liquids and slurries, are kept in suspension using magnetic stirrers, while specially designed pumps, draw precise amounts through specially engineered parallel glass slides (flowcell). Our particle measurement systems have superior resolution, compared to laser diffraction, allow for precise analysis of particles as small as 200 nanometers, which makes this technology not only suitable, but preferable for exacting applications like protein aggregate characterization.

OCCHIO ZEPHYR SERIES DYNAMIC PARTICLE MEASUREMENT SYSTEMS

DIGITAL IMAGING TECHNOLOGY CAN BE ESPECIALLY USEFUL FOR PARTICLE SIZE DISTRIBUTION TESTS, IN CASES WHERE THE PARTICLES ARE TOO SMALL FOR ANALYSIS BY LASER DIFFRACTION, OR WHERE THE ANALYSIS OF PARTICLE SHAPE PARAMETERS IS IMPORTANT.

THE REALTIME CAPABILITIES OF OCCHIOS' PARTICLE CHARACTERISTIC ANALYZERS, ALONG WITH THE ABILITY TO DETECT SHAPE PARAMETERS, AND MAKE DISTINCTIONS BETWEEN LIGHT AND DARK, ALLOW FOR THE ADVANCED ANALYSIS OF PARTICLES IN BOTH LIQUID AND SOLID FORMS

RECENT INNOVATIONS INCLUDE THE ABILITY TO MEASURE TRANSPARENT CRYSTALS IN CRYSTALLIZATION STUDIES, DYNAMIC PROTEIN AGGREGATE ANALYSIS AND ABSOLUTE PARTICLE COUNTING OF PROTEIN AGGREGATES..                                         
                                                                  
BY OVERLAYING VIRTUAL CIRCLES ON TO PARTICLE IMAGES, QUANTIFIABLE ABRASION PROPERTIES LIKE BLUNTNESS AND ROUGHNESS ARE NOW POSSIBLE. KINETIC MEASUREMENTS OF SLURRIES, AND LENGTH / WIDTH ANALYSIS OF FIBROUS MATERIALS, ARE ALSO POSSIBLE. NEAR PERFECT SIEVE CORRELATION IS ATTAINED BY USING THE MAXIMUM INSCRIBED DISC, TO DETERMINE THE WIDEST PART OF A PARTICLE, WHICH WOULD DETERMINE THE APERTURE SIZE A PARTICLE WOULD FALL THROUGH.
SUITABLE MATERIALS:

FREE FLOWING POWDERS & GRANULARS

LESS DENSE POWDERS THAT TRAVEL WELL IN FLIGHT, BUT DISPERSE EASILY

EXAMPLES: SAND. SUGAR, COFFEE GRINDS
A TELECENTRIC LENS PROVIDES THE SAME MAGNIFICATION LEVEL AT ALL DISTANCES
BY OVERLAYING VIRTUAL DISCS ON TO IMAGES OF ABRASIVE PARTICLES, ABRASIVE PROPERTIES LIKE BLUNTNESS AND ROUGHNESS, CAN BE STUDIED.
USING THE MAXIMUM INSCRIBED VIRTUAL DISC OVERLAY, NEAR PERFECT SIEVE CORRELATION MAY BE ATTAINED. (VARIANCES ARE CAUSED BY SIEVE APERTURE DIAGONALS, WHICH GIVE A FALSE READING)
Occhio Particle size and shape analyzers, are the collaboration of many years of focused research in the fields of optics, lighting, and digital imaging. Using a collimated (parallel beam), and variable, monochromatic backlight, in conjunction with a high speed, telecentric lens camera, and sophisticated software, extremely robust particle definitions are made possible. Newly defined parameters, such as bluntness, luminance, and solidity, are now available, as well as traditional measurement parameters, like length, width, and particle count.
SUITABLE MATERIALS:
LARGER AND MORE DENSE PARTICLES / ITEMS THAT 
DISPERSE EFFECTIVELY IN GRAVITY

EXAMPLES: GRAVEL, SHREDDED CHEESE, NAILS
THE BLUE MONOCHROMATIC LIGHT PROVIDES PARTICLE DEFINITIONS BELOW 1 MICRON, WHICH CANNOT BE ACCOMPLISHED WITH THE STANDARD WHITE LIGHT USED BY OTHER DIGITAL IMAGERS

THREE SEPARATE MODELS DESIGNED FOR MATERIALS WITH DIFFERENT DISPERSION  REQUIREMENTS 
All Occhio Particle Analyzers use the same Callisto Software, enabling advanced size and shape detection and measurement on a variety of materials.
Using special mono-chromatic back lighting techniques to obtain superior definition, Occhio Analyzers are able to detect particle shapes and sizes not attainable with standard white lighting.

DISPERSION
It is difficult to take a,"ONE SIZE FITS ALL" approach to sample dispersion. The particles must be physically separated before the are presented to the optics.
The ZEPHYR ESR Analyzer, is designed to provide optimum dispersion for larger, and more dense particles like gravel. The flow rate of the sample is monitored, 
and controlled automatically. Standardized SOP's are created for each different sample type, making repeat testing a breeze.

DISPERSION
The ZEPHYR Analyzer was designed for free flowing powders and smaller granulars (sugar) that are
not too large or dense to travel horizontally. A powerful vacuum pump whose inflow is forced between two plates in front of a camera is an alternative system to horizontalchute dispersion, when high throughput is needed. 

Particle orientation is fairly well controlled and particle dispersion is excellent. Instead of a relying on a delicate sampling operation to reduce the amount of material to a few tens of grams as required for the horizontal chute, this principle allows a user to analyze larger quantities of material (kg) by taking images at regular intervals. Humid, dirty and sticky materials are acceptable as feed. 
BY USING AN ANTI STATIC DISSIPATIVE COATING ON THE HOPPER SURFACE, AND ATTACHING A PRE-DISPERSION SIEVE BELOW THE FUNNEL, SAMPLE AGGLOMERATION IS  
​VIRTUALLY ELIMINATED,EVEN IN DIFFICULT SAMPLE TYPES.​ INSTEAD THE SAMPLE "PEPPERS" ON TO THE HOPPER, PROVIDING AN EVEN STREAM.

OCCHIO DIGITAL IMAGE ANALYZERS HAVE THE ABILITY TO DETECT AND QUANTIFY BOTH PARTICLE SIZE AND PARTICLE SHAPE, PAVING THE WAY FOR THE ADVANCED ANALYSIS OF PARTICLES IN BOTH LIQUID AND SOLID FORMS.

CORRELATIONS TO OTHER PARTICLE SIZE ANALYSIS METHODS, LIKE SIEVE ANALYSIS AND LASER DIFFRACTION, ARE SEAMLESSLY EMPLOYED. EVEN SHAPE PARAMETERS LIKE LENGTH, FLATNESS, AND ANGULARITY IN AGGREGATES, OR THE LENGTH OF STRINGY PARTICLES LIKE SHREDDED CHEESE, OR TOBACCO, ARE POSSIBLE.

ONCE A BASIC CORRELATION HAS BEEN ESTABLISHED, THE RESULTS ARE FINE TUNED WITH THE OCCHIO CORRELATION PROGRAM, ALLOWING FOR TURNKEY SOLUTIONS TO PARTICLE CHARACTERIZATION.
