Insitec D

Summary

Insitec D provides robust, reliable on-line particle sizing for dry powder applications and is ideal for process optimization and control applications.

Compliance with the new ATEX regulations (99/92/EC and 94/9/EC) – mandatory for existing workplaces from July 2006 – results for the first time in the zoning of areas that are potentially explosive due to the presence of dust. The Insitec D has been approved for Zone 22 use (Category 3 approval), and is expected to be approved for Zone 21 use (Category 2 approval).

Features

• Simple-to-clean cell and flow path facilitated by triclamping and the use of 316L stainless steel in the manufacture of all metallic parts
• Sample path and optical head are easily and quickly assembled and disassembled by hand without the use of tools (no screws used on user serviceable parts)
• Parts that are easy to clean and visually inspect
• Uniform and highly polished surfaces to minimize powder build-up in the sample path
• Clean In Place (CIP) / Sterilize In Place (SIP) options
• Validation and 21 CFR part 11 options

• In-process or off-line measurement of particles suspended in a gaseous stream using laser diffraction
• Size range 0.1 to 1000 µm
• Model independent analysis
• Patented high concentration sizing method using a correction for multiple scattering
• 4 measurements per second of the complete particle size distribution based on thousands to millions of particles per minute
• First principles measurement using rigorous Mie theory. No calibration required
• Rigorous measurement technique has been validated for pharmaceutical use
• Changeable lenses in the sensor allow configuration of instrument resolution to individual process needs
• ATEX badged (Ex II 3 D EEx tD A22 IP65 T120°C)
• Watertight and dustproof to industrial protection rating IP65 (optical head to IP66)
• Optical head and sample path certified to Pressure Shock Resistance of 11bar(a) (PSR11)

Robust, repeatable and representative sampling is the key to good measurement, making the process interface a critical part of the Insitec system.

Each process interface is customized to the process and automated to minimize operator intervention.

Continuous sampling:

• Range of process interfaces allow sampling directly in-line, on-line using eductor, or special samplers such as screw augers
• Continuous on-line particle sizing in bulk powders with mass flows from 1kg/h to 500t/h
• Eductor interface contains no moving parts and delivers the correctly dispersed powder to the instrument, continuously
• Customized design for abrasive, fragile and cohesive materials
• Dry flow cell technology has successful 10 year track record in industrial processes. Range of available flowcell path lengths (line i.d. of 25 – 50 mm standard, >50 mm special projects) for in-line applications
• Purge keeps windows clean from dust, minimizing routine maintenance
• 10 bar max operating pressure capability

• Full automation and integration into plant control systems
• RTSizer software interfaces with plant control systems through Malvern Link automation package
• Award-winning Intellution iFix SCADA license delivered with every process system. This gives enormous flexibility in controlling instrument, sampling system and linking to the plant control system

The Insitec D is designed from the outset for industrial use. The rugged construction and robust technology reflect the exacting demands placed on an analytical instrumentation that is in continuous use in a process environment. Capable of taking scattering patterns every second and delivering the particle size distribution in real-time, an Insitec D can make more than a million measurements every year. The instrument, the process interface, analysis software, automation and data reporting can all be customized to the unique needs of individual clients.
