The MicroNIR PAT-W spectrometer is a fit-for-purpose near-infrared (NIR) analyzer for quality-by

-design (QbD) manufacturing. The spectrometer is a sturdy, scalable, next-generation system for

real-time process monitoring in blend homogeneity, content uniformity, loss on drying, roller

compaction, and similar process analytical technology (PAT) applications.

 

With the well-established Viavi linear variable filter (LVF) technology, the PAT-W has the smallest

form factor among commercial process monitoring instruments in a fit-for-purpose design.

This makes it ideal for use with processing equipment of a variety of sizes, with the stability and

performance to facilitate efficient and smart manufacturing.

The user-friendly MicroNIR PAT-W was engineered to handle today's challenging GMP-regulated environments yet requires minimal system maintenance. There are no expensive fiber optic cables or moving components, enabling superior instrument stability and performance in challenging process environments.
