EQUIPMENT FOR QUALITY CONTROL AND R&D  500 NANO PARTICLE CHARACTERIZATION SYSTEM FOR SMALL PRECISE AMOUNTS OF FINE POWDERS TO 400 nm BROCHURE AND DATA SHEET 500 NANO

Occhio Digital Imaging Analyzers are uniquely suited for  particle size, shape, and distribution analysis, in the range of 200 nm to 3.0 mm. Depending on the size of the particles to be analyzed,  what form they are in, ie...liquid or solid, and the volume of the sample, different dispersion techniques are employed relative to the required throughput, to provide optimal conditions for image capture.

The 500 NANO Analyzer is specifically designed for static, non destructive analysis of low volumes (Down to 1 ml) of very fine powders. The sample is placed in a small cup with a tearable membrane floor.

​A special vacuum pump is then used to tear the membrane, and deposit millions of particles on a glass slide, in just a few seconds.

The integrity of the powder is maintained, while agglomerates are gently dissociated, providing good orientation, and natural sedimentation on the glass slide. SPECIAL DISPERSION CUP ALLOWS FOR SAMPLES AS SMALL AS 1ml TO BE ANALYZED. NANO 500 POWDER ANALYZER  SAMPLE TYPE: VERY FINE POWDERS DRY 400 nm to 2 mm 

SAMPLE TRANSPORT METHOD: SPECIAL NON DESTRUCTIVE VACUUM  PUMP AND TEAR ABLE MEMBRANE DISPERSION  ​​What is unique, compared to other methods, specifically  laser diffraction , and  sieve analysis , is the ability to detect particle shape, instead of making the practical, but false assumption, that all particles are spherical. 

When you have the ability to measure, and quantify, particle shape parameters, particle size takes on a whole new meaning.  THREE REASONS TO TAKE PARTICLE SHAPE IN TO CONSIDERATION  WHAT IS UNIQUE WHEN COMPARED TO LASER DIFFRACTION AND SIEVE ANALYSIS WHAT IS UNIQUE COMPARED TO OTHER DIGITAL IMAGING DEVICES 1- PARTICLE SHAPE AFFECTS THE PERFORMANCE ATTRIBUTES OF THE FINISHED PRODUCT  

BES IDES AFFECTING POWDER FLOW AND MIXING PROPERTIES, PARTICLE SHAPE IS CRITICAL IN THE EVALUATION OF MATERIALS LIKE ABRASIVES, WHERE THE THERE IS REDUCED PERFORMANCE AS THE PARTICLE IS CLOSER TO   BEING SPHERICAL. AFTER YEARS OF RESEARCH IN OPTICS AND LIGHT,  OCCHIO  DEVELOPED A SPECIAL MONOCHROMATIC BACK LIGHT TO PROVIDE SUPERIOR PARTICLE DEFINITION. COMPARED TO NORMAL WHITE LIGHT,. ALLOWING THE DETECTION OF PARTICLES BELOW 1 MICRON.

THE BLUE LIGHT SOURCE IS COLLIMATED, AND ACTS LIKE A CALIPER, MEASURING ALL FACETS OF EACH PARTICLE IN HIGH DEFINITION.  NEWLY DEFINED SHAPE PARAMETERS INCLUDE ROUGHNESS, AND BLUNTNESS ANALYSIS IN ABRASIVES, WHERE THE DEVIATION FROM SPHERICITY IS MEASURED, ALONG WITH THE SHAPE OF THE ASPERITIES.  2-SHAPE INFORMATION ALLOWS FOR BETTER CORRELATION TO EXISTING METHODS

MANY INDUSTRIES HAVE THEIR STANDARDS DEFINED BY SIEVE ANALYSIS. SO ALTHOUGH LASER AND DIGITAL IMAGING PROVIDE FOR MORE COMPREHENSIVE ANALYSIS, MORE ACCURATE, THEY STILL NEED TO BE ABLE TO CORRELATE TO SIEVE RESULTS.

LEFT-OCCHIO USES THE CONCEPT OF THE MAXIMUM INSCRIBED VIRTUAL DISC, TO MEASURE THE WIDEST PART OF THE PARTICLE, WHICH WOULD INDICATE WHICH SIEVE APERTURE THE PARTICLE WOULD BE RETAINED BY.  LASER DIFFRACTION DOES NOT HAVE THIS CAPABILITY.

3- PARTICLE SHAPE ANALYSIS ALLOWS FOR NEW OPPORTUNITIES IN R&D, AND QUALITY CONTROL PRODUCT DEMONSTRATION

Each analysis may be defined as an SOP, so that frequent tests can be run by several operators, with no need for programming, and the same results every time.

After running an analysis, the comprehensive analytical software package  Callsito tm  creates detailed reports, in a variety of useful chart formats, including bimodal, boxplot, scatter plot, and 3-D, showing shape and size distribution by number, and or percentage.
