The new Parsum IPP70 in-line particle size analyzer is a new addition to the Parsum range available from Malvern Instruments. The new probe extends the variety of applications for which Parsum systems provide ideal solutions for particle measurement.

Based on the theory of spatial filter velocimetry, the IPP70 measures particulate materials in the size range 50 to 6000 microns. Robust and easy to use, it is suitable for the continuous monitoring of a range of unit operations, including wet and dry granulation, coating and spray drying.

The IPP70 probe is inserted directly into a process line or vessel. It has been used successfully for monitoring both batch and continuous processes, for materials as diverse as polyethylene and washing powder. The instrument continuously tracks Dv(10), Dv(50) and Dv(90) making it ideal for endpoint detection, process control and process optimization applications.

The fibre optics at the heart of the IPP70 deliver consistent measurement at high particle loadings. Sensitivity to fluctuations in loading is low, making this an extremely robust solution. Highly accurate data is produced at a measurement rate up to 15000 particles per second.

A rugged outer design protects the IPP70 from the process environment, for proven high reliability. New software delivers user interfaces that are designed specifically to meet the needs of both the process and the research environment.
