Viavi MicroNIR PAT-L

Immersion Spectrometer: A robust near infrared (NIR) process spectrometer for liquid analysis

Rugged, fast, and maintenance-free, the MicroNIR PAT-L transmission spectrometer is designed for real-time process monitoring in industrial and pharmaceutical process analytical technology (PAT) applications.

The PAT-L is the newest member of the VIAVI PAT family of miniature process spectrometers. Its compact design and high performance make it ideal for use in industrial processes that require continuous monitoring.

The NIR transmission design permits analysis of aqueous and nonaqueous liquids. The PAT-L is available in multiple configurations, specified on order, with a choice of probe material, optical path length, immersion depth, and process flange.

As a member of the MicroNIR product family, it enables moving directly to production chemometric models and processes developed elsewhere. The PAT-L integrates readily with process equipment of all types and sizes, with the performance and stability to support truly efficient-and scalable-manufacturing.

Software

The software suite allows for deployment flexibility from process/product development to manufacturing environments and features audit trails, comprehensive user management, encrypted secure data storage, and many other capabilities required for regulated GMP environments.

• The MicroNIR PAT control software enables easy data acquisition, method investigation, user management, method development, instrument performance qualification per USP 1119 criteria, and the visualisation of moving block standard deviation (MBSD) trends.
• Viavi Unscrambler® X Lite regression and classification software provides a complete set of chemometric tools for calibration model development and data investigation, supporting MBSD model development with %RSD and PCA-based blending tools.

Mounting and Process Integration

The MicroNIR PAT-L has been designed for maximum flexibility to meet the diverse requirements of process integration. A variety of flange mounts and probe lengths are available. Probe body materials include 316L stainless steel and Hastelloy C22. Transmission gaps range from 2mm (for aqueous liquids) to 3,4,5, and 10 mm (for polymers and petrochemicals).
