New mobile on-line particle size analyser

The Insitec Voyager is the latest addition to Malvern Instruments Insitec range of on-line particle size analysers, allowing sampling at various points in a production line using a single system

The Insitec Voyager is the latest addition to Malvern Instruments Insitec range of on-line particle size analysers.

This mobile system, which won the Most Innovative Product award at the recent Asia Pacific Coatings Show 2003, can be attached to fixed sampling ports at a variety of points in a production line.

It can also be used to sample from different production lines within the same manufacturing plant.

The Insitec Voyager is the first ever standard mobile unit for real-time on-line particle sizing.

It can be used on-line and at-line.

The system is ideal for customers managing sites where there are many manufacturing lines requiring optimisation, or for first-time buyers who would like to evaluate the use of on-line particle sizing for their application.

The mobile Voyager, which measures just 1.2 m x 0.8 m x 0.6 m, uses the same proven technology and rugged platform that is the foundation for all the Malvern Insitec range of on-line particle sizers.

The Voyager unit houses all the instrumentation and software needed for on-line particle size analysis and can be moved easily around a plant.

Voyager is suitable for use even in highly regulated environments.

It meets current GAMP requirements, with a simple to clean cell and flowpath.

The system features triclamping and 316 stainless steel parts for easy cleaning and its software enables full compliance with the FDA 21 CFR Part 11 requirements.

On-line particle sizing facilitates real-time optimisation of process parameters and configurations.

Being a laser diffraction-based system, Malvern Insitec offers benefits in that the technique requires no calibration nor does it need the long data acquisition intervals that can mask true process behaviour.

With laser diffraction techniques, laser light is scattered by particles in the sample and the angular intensity is measured by a series of photodetectors.

Smaller particles scatter light at greater angles than larger ones and the resulting diffraction pattern is used to measure particle size.

By applying the rigorous Mie light scattering theory to the data, the complete particle size distribution can be ascertained.
