The Malvern Insitec LPS on-line particle size analyser is designed to meet the growing demand for on-line particle size analysis in liquid process streams.
In the past, continuous, real-time particle size measurement has been used primarily for dry processes. The introduction last year of the Insitec LPS has provided a new option for continuous measurement that can be fully integrated into liquid process streams.
A reliable and robust laser diffraction-based system, the Insitec LPS can be used off-, at-, in- or on-line for a very wide range of processes. It can even be used to measure in concentrated, hot, sticky process streams operating under pressure.
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 while avoiding dilution shock. These components have few moving parts, are self-cleaning and are designed to minimise 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 analyser. With abrasion-resistant, self-cleaning sapphire windows, and a purge to prevent condensation, the analyser requires no calibration and little maintenance.
In common with all Insitec systems, the Insitec LPS is designed for continuous industrial use. 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.
