New Insitec LPS provides complete solution for continuous wet particle size measurement


Many industrial particle sizing applications now require the continuous measurement of particle size in liquid streams. To provide a complete solution for this requirement, Malvern Instruments has introduced the new Insitec LPS (Liquid Process Sizer).

Designed for continuous industrial use at- or on-line, the Insitec LPS can accurately and reproducibly measure a very wide range of process streams, from highly concentrated mineral slurries through to lipid emulsions. Each component of the system – sampler, pre-diluter, cascade diluter, measurement cell, and software – can be individually tailored to the process, ensuring that even the most challenging applications can be tackled effectively.

The Insitec LPS sampler extracts 2.5 ml liquid slugs from the full pipe section. There is never any cessation of sample flow, thus avoiding blockages. The process interface is designed for high pressure (where necessary) and for easy installation and maintenance.

The Insitec LPS pre-diluter and cascade diluter work together to bring the sample to an optimal concentration for analysis whilst avoiding dilution shock. These components have few moving parts, are self-cleaning and designed to minimize diluent consumption. Consistent dilution is achieved efficiently with no manual intervention.

At the heart of the Insitec LPS is Malvern’s proven and industrially rugged Insitec laser diffraction-based particle size analyzer. With abrasion-resistant, self-cleaning sapphire windows, and a purge to prevent condensation, this is an analyzer designed for 24/7 operation. It requires no calibration and little maintenance. The data produced are presented using established Malvern Link and RTSizer data handling systems. Integration with existing control platforms is straightforward, and so is customized data presentation.
