Malvern Launches New Generation Image Analysis System for Particle Shape Measurement
Malvern Instruments Ltd (Malvern, Worcs, England) has launched a new generation image analysis system for the fully automated characterisation of particle shape and size. The Sysmex FPIA-3000 builds on the success of the existing Sysmex FPIA-2100 flow cytometry-based analyser, added new features and extending the range of applications. In addition to the laboratory system, a remote option will be available for use in at-line situations.
Particle shape analysis has become a critical parameter in many industrial processes. This has fuelled demand for increasingly flexible analytical systems that can be used in a variety of different circumstances to provide maximum shape and size information quickly and easily.
Key amongst the new features is the system's ability to measure across a wide particle size range. The standard instrument configuration allows the characterisation of particles from 1.5 microns to 160 microns. High and low magnification options cover the ranges 0.8 microns to 80 microns and 12 microns to 300 microns respectively.
Sample volumes as low as 0.5ml can be used throughout and every single particle image is now stored for future reference and analysis. Powerful new software brings access to a whole range of new shape and size parameters not previously available, as well as improved threshold control that allows more sensitive edge detection for transparent particles.
The system operates using the same principles as its predecessor, measuring particles suspended in aqueous and non-aqueous liquid media. Using a CCD camera, the system produces images of each suspended particle. Samples pass through a sheath flow cell that transforms the particle suspension into a narrow, flat flow, ensuring that the largest area of the particle is oriented towards the camera and that all particles are in focus. Measurement is complete in just two and a half minutes.
