Customised Laser Diffraction Sizing of Wet Suspensions
The introduction of the new Malvern Insitec L adds particle sizing in wet suspensions to the capabilities of the Malvern Process Systems range of laser diffraction based on-line particle size analysers for measurements in the size range 0.5 to 1,000 microns.In common with all other systems in the range, the Insitec L is built on the established Insitec platform, described as a rugged and robust system that was designed from the outset for industrial applications and which is in widespread use for on-line measurement in dry powder processes.
Insitec L takes advantage of the proven liquid suspension flow cell employed in Malvern's laser diffraction-based Mastersizer systems and used routinely across a wide range of industrial applications and materials. The wet cell can be positioned directly in-line for dilute process streams and used on-line with suspensions, where applications include quality control of minerals and in precious metals grinding.
A range of flow cell path lengths, from 0.2mm to 4mm, is available to suit the specific particle size distribution of the process material. Quick-release flow cell mountings - with easy access to the cell - allow trouble-free cleaning and maintenance. Cell maintenance is in any case minimised through the use of windows that are said to be very simple to change - and a choice of either glass or sapphire windows meets individual abrasion resistance requirements.
The Malvern Insitec range offers on-line particle size analysis for a diverse range of applications. In addition to the standard Insitec B and the new Insitec L, the Insitec T meets the exacting specifications necessary for use in GMP operations, while the Insitec X additionally features Intrinsic Safety, for environments where explosion hazards might otherwise pose a problem.
