MicroNIR PAT-Ux

A robust near infrared (NIR) process spectrometer for use in hazardous locations.

Rugged and safe in hazardous locations, the MicroNIR PAT-Ux process spectrometer is designed for real-time process monitoring in pharmaceutical, industrial and food process analytical technology (PAT) applications.

The PAT-Ux is the hazardous location version of the popular VIAVI PAT-U miniature process spectrometer. Safe in the presence of flammable gases, vapors, fibers,

or dust, the PAT-Ux enables moving a process directly to production in a hazardous location using chemometric models and processes developed in the ordinary

location of a laboratory. The PAT-Ux attaches readily to fixed processing equipment of all types and sizes, with the performance and stability to support truly efficient – and scalable – manufacturing.

Benefits

  • Non-invasive, real-time NIR analysis forhazardous manufacturing locations
  • Safe in the presence of flammable gases, vapors, fibers, or dust
  • ATEX, NEC, and IECEx certified
  • Interoperable with all MicroNIR instruments
  • Maintenance-free with no moving parts
  • Robust, reliable, repeatable
  • Washable, IP65 & IP67 rated instrument head
  • Easy Ethernet and power connections

Applications

  • Pharmaceutical Manufacturing
  • Fluid bed drying
  • High shear mixing
  • Granulation
  • Food and Feed Manufacturing
  • Grain & flour processing
  • Moisture, protein, fat, and sugar analysis
  • Industrial Processing
  • Explosives manufacturing
  • Polymers & petrochemicals

The MicroNIR PAT-Ux for hazardous locations consists of two main parts: The spectrometer instrument head and the barrier box. The instrument head is identical to the well-established MicroNIR PAT-U with the addition of a wiring adapter for hazardous locations. The barrier box houses the interface electronics in a heavy, cast aluminum enclosure. The barrier box is hardwired to the instrument head and has user-available ports for connections to Ethernet, 24VDC power, and optional external trigger. The barrier box comes with mounting brackets for attachment to process equipment.

Software:

Like all MicroNIR instruments, The PAT-Ux includes the VIAVI MicroNIR Pro software suite with features for data acquisition, calibration and method development, user management, and real-time prediction. MicroNIR Pro software supports instrument performance qualification (IQ/OQ) per EP 2.2.40 and USP 1119 test criteria and tools enabling Title 21 CFR Part 11 compliance. An enhanced OPC interface is optionally available for integration with process control systems.

Process Integration:

The MicroNIR PAT-U can be mounted to process equipment sanitary flanges using a collet assembly and triclover clamp. A weld-in flange kit with sapphire process window is also available. Installation in hazardous locations requires trained and/or certified personnel according to local regulations.
