ALPAGA 500 NANO

The best solution for measuring powders

By a team focused on powder characterisation

Tanks to an international and multidisciplinary team of engineers, OCCHIO offers you a complete range of solutions, starting from 500 nanometers and extending up to centimetres.

Whether it is for laboratory instrumentation,"at line" or even "on line" solutions, OCCHIO would be privileged to be your partner in high-level powder charactersation.OCCHIO and ALPAGA 500 NANO will bring you accuracy, benefit and innovation.

_Accuracy

With its proprietary Ultra-Violet Collimated Light (UVCL) and high quality telecentric lens, ALPAGA 500 NANO will change your own perception of image analysis, measuring particles which are invisible under normal microscopy.

._Benefit

ALPAGA 500 NANO is a fully automatic device dedicated to powder quality characterization. it is easy to use and carries out rapid analyses in under 2 minutes. ALPAGA 500 NANO is able to accurately measure very small samples, below 1 melligram of pharmaceutical powder.

_Innovation

Morphology measurement is more than shape description. To improve, you need robust and significant measurement. Based on decades of university research, the ALPAGA 500 NANO provides your R&D department with dedicated parameters specially engineered for your industrial purposes.

Size and morphometric measurements

_Size

Performed by computing the maximum inscribed disc within a particle. The algorithm developed is exclusive to OCCHIO. It is extremely robust, allowing ALPAGA 500 NANO to compute real size distribution curves with an unrivalled accuracy.

_Elongation

Thanks to its robustness,the elongation measurement obtained from ALPAGA 500 NANO,is computed from one minus the ratio between inertial ellipse axes.

_Roundness

It is based on a very accurate measurement of local curvature and takes into account the fact that blunt asperities are more significant than very acute ones. The roundness index is the expression of maturity in an abrasion process.

_Roughness

Defined like the ratio between the blunted surface by the entire surface of the grain, this parameters measure acute asperities for each particle.

_Convexity

It is based on the convex shape made by a virtual rubber band fitted on each particle. It is defined like one minus the ratio between convex area and real area of the grain.

VDD 270

This newly-patented disperser will provid you with perfectly prepared slide glass. Without any sample damage, this Vacuum Disperser Device (VDD) will gently deposit millions of individual grains of powder on a lide glass within a few seconds. The device is rapid and easily cleaned. Sample supports and rings are cleaned in a class 100 whit room, guaranteeing the eliminating of contamination or measurement artefacts.

Dispersal

_ Respect the integrity of the powder. There is no impact; the VDD 270 uses the vacuum strength to softly dissociate agglomerate.

_ Good orientation of each individual particle with natural sedimentaion on the sample glass.

_ Avoid contamination with an easily cleaned design. The entire system is made from stainless steel so that every part can be easily cleaned in the washing machine without risk of breakage.so that every par

_ Wipe away artefacts with perfectly cleaned sample glass.All glass is prepared in a class 100 white room.

_ Reduce sampling variability; our engineers take the latest developments in sampling theory into account in our product development programs.

ALPAGA 500 NANO

ALPAGA 500 NANO provides you with high quality images with a real resolution of less than 500 nanometers. The entire system is engineered to remove diffraction so that a clear and prescise cut of each particles's outlines is quickly obtained.

Image acquisition

_ Use the best progressive scan high-resolution camera on the market;1392*1040 effective square pixels with a sensitivity of 0.3 lux.

_ Remove diffraction with monochromatic ultra violet backlighting illumination.

_ Increase the quality of the particle's outlines with collimated light and telecentric lens.

_ Be perfectly focused on each particle thanks to an innovative light-lens combination.

_ Use the entire range of pixel values to obtain a perfect threshold.

_ Avoid vibration problems due to the high-speed camera shutter,up to 1/200 000 sec.

_ Reduce maintenance costs and increase robustness with a fixed camera an light.

CALLISTO

CALLISTO,the embedded image analysis software with its unrivalled morphologic descriptor,computes 16 dedicated parameters for you. These parameters were engineered to be significant, robust and linked to physical properties.

Measure
