Inline particle probe IPP 70 – Standard particle probe for measurement in high loaded particle streams in the range of 50μm to 6mm, also available as ATEX version (Zone 0/20)
Inline particle probe IPP 80 – Pharma version, for use in a GMP environment and wherever high hygienic standards are required
Process interface – Accessories such as purge cells and inline dispersers allow measurement even in dense, moist and sticky particle streams. The direct dispersion in the process sets the Parsum probes apart from other in-line measurement systems
Parsum probe IPP 80 for monitoring the particle growth during batch granulation in a fluid bed system for the production of tablet press compounds
Use of 2 inline particle probes IPP 70 for monitoring and controlling a continuous fluidized bed granulation. The measurement takes place in the drying zone and at the product outlet
Whereas conventional laboratory analysis is designed to determine the particle size in order to obtain information regarding the quality of the end products or intermediate products respectively, in-line particle measurement provides information on the manufacturing process that is often decisive. Based on this information, you will be able:
- To better understand and more efficiently operate your processes
- To make more economic use of your resources and to reduce your process times
- To quickly detect defects, and to react to them accordingly
- To minimize your risks and enhance your safety
- To apply closer specifications and to increase the capacity utilization rate of your facilities
- To enhance your reproducibility and improve your batch-to-batch consistency, and to expedite your developments and to reduce your upscaling times
The core of the measurement principle is the fiber-optic spatial filter technique developed, patented and enhanced by Parsum.
The array (spatial filter) illuminated by a laser will detect optical signals from single particles from which the specific velocity and the chord length will be determined for each particle. A circular buffer is provided to continually convert the individual measurements into a "sliding" particle size distribution.
Sampling rates of up to several thousand particles per second will guarantee a high confidence level.
The user will see a continuous representation of the particle size trend, like watching a movie, to get a better insight into his process. Comparisons to laboratory measurements such as laser diffraction or granulometric analysis, viz. the "snap-shots" of the process, can be done at any time.
Types of Probes
This probe has been designed to measure the particle size distribution of powders, pellets or granules respectively in pharmaceutical processes. This probe is a valuable PAT tool wherever especially high requirements are made on cleanliness, cleanability or hygiene, be it the conventional batch operation or continuous production. ATEX certified for Zone 0/20.
This universal in-line particle probe is designed for direct use in dense particle flows, in fluidized beds or similar processes. The IPP 70 is self-monitoring during the measurement. LEDs on site or signals to the process control system respectively will always enable the user to monitor the safe operation of all major components.
This ATEX certified and intrinsically safe probe is designed to provide reliable particle measurements in explosive atmospheres. Direct measurements can be made in Zones 0 and 20.
A wide range of accessories for process adjustment such as in-line dispersers or purge cells, used as a process interfaces, will facilitate adjustment to a variety of conditions.
It is the ability to disperse the particle flow in the process vessel that sets the Parsum probes apart from other in-line measurement systems. It is only through in-line dispersion that it will be feasible to reliably determine the particle size in moist or sticky materials in a manner comparable to laboratory techniques.
