The main applications of the MicroNIR PAT-W spectrometer are as follows:

Pharmaceutical Manufacturing

  • Blend uniformity
  • Content uniformity
  • Fluid bed drying
  • Granulation

Food and Feed Manufacturing

  • Moisture content
  • Nutritional assay
  • Protein
  • FatIndustrial Processing
  •  Polymers
  •  Petrochemicals
  • Reaction monitoring


The MicroNIR PAT-W spectrometer is a fit-for-purpose near-infrared (NIR) analyzer that is meant 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, compaction, and other 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 no moving components, thus enabling superior instrument stability and performance in challenging process environments. Its stainless steel/brushed aluminum cabinet is water and dust resistant according to IP67 standards and cleans easily.
