PICTIS is a unique combination of high speed image analysis with gentle dry dispersion by the built-in gravity disperser, optimised for at-line or on-line applications with sensitive or fragile dry particles;

Technical specifications and dimensions.

PICTIS combines the high speed image analysis of QICPIC with the gentle dry gravity disperser GRADIS/L in a single robust instrument, specially designed for at-line or on-line applications in the process environment. PICTIS is directly operating with manual or automatic feeds, e.g. by external robots, delivering samples to the inlet hopper of the VIBRI/L-GMP dosing unit.

The particles are fed at constant mass flow by the integrated dosing unit into the gravity disperser. Here, the particles are accelerated by gravity of earth and gently dispersed by particle-to-particle and particle-to-wall collisions at impact plates of the fall shaft of the disperser.

Like QICPIC it combines well established with innovative techniques: A dry gravity disperser (well proven in many HELOS applications); a pulsed light source with an extremely short exposure time of less than 1 ns which enables clear cut images from fastest particles created by the dispersion process (100m/s would result in only 100 nm of motion blur); a high speed camera suitable to measure up to 450 images per second for high statistical relevance of the measured results and short analysis times.

PICTIS covers particle sizes between 5 µm and 10 mm in three measuring ranges. The primary measurement data are stored in 100000 primary classes and can be evaluated in individually definable formats. Pre-defined sets of size classes allow an easy adoption to existing measurement specifications.

The WINDOX software offers simultaneous calculations of all relevant size and shape characteristics. A particle gallery in combination with multiple filter functions supports the evaluation of specific results, even if very large amounts of 10 million particles or more are stored.

PICTIS fulfils the security requirements of the FDA and is compliant to 21 CFR Rule 11.

Highlights of PICTIS

	Particle size and shape analysis from 5 µm to 10,000 µm.
	Direct cooperation with simple sampling probes.
	Efficient dispersion instead of software-based particle elimination or correction.
	Quasi-static image analysis in a high speed particle stream.
	Clear outline of particles, independent of the position in the measuring zone.
	Definite borders of particles, black outline, transparent particles are no problem.
	Very low statistical errors due to very high particle numbers.
	User defined class limits out of 100000 primary size classes, free definition of sampling points, pre-defined sets of class limits are shipped with the software (e.g. HELOS classes, sieve classes, etc.)
	A large number of evaluation modes are available, evaluation modes are selectable even after the measurement: particle size: basing on equivalent projected circle area, Feret diameters, etc. particle shape: sphericity, aspect ratio and convexity fibre evaluation: fibre length, fibre diameter, straightness, and elongation even of complex structures. particle gallery: displays and prints a user defined selection of particles along with definable characteristic data user specific evaluation: performs the evaluation of particle size and shape only on particles matching user defined filter conditions.
	PICTIS fulfils the security requirements of the FDA and is compliant to 21 CFR Rule 11.
	Rigid full stainless steel housing with integrated control box allowing for the operation of the sensor in industrial environment.
	A GMP version is available as an option.
