PAT-W MicroNIR Spectrometer
Continuous process control
- compact
- intégratable
- real time results
MicroNIR PAT-W is a NIR (near infrared) spectrometer. A rugged and scalable wireless system used for real-time monitoring of manufacturing processes such as blend homogeneity, uniformity, drying loss, roll compaction and similar applications. Its Linear Variable Filter (LVF) technology makes the PAT-W an ultra-compact, high-performance sensor that integrates directly with process equipment to facilitate efficient and intelligent manufacturing (QbD).
Designed to handle harsh GMP-regulated environments, the PAT-U spectrometer requires minimal maintenance. There are no expensive fiber optic cables or moving components, allowing for superior stability and performance in complex environments.

Compliance for regulated environments
Designed to be integrated into harsh GMP regulated environments, the PAT-U spectrometer requires minimal maintenance. There are no expensive fiber optic cables or moving components, allowing for superior stability and performance in complex environments.

Standard mounting
This integration requires a weld in the flange, a sanitary flange bracket, a sapphire window and a retaining ring with O-rings. The flange is welded into a hole cut in the mixer cover, then the sanitary flange bracket, window and retaining ring are assembled. Then the PAT-W is secured against the window and a sanitary flange with a standard tri-clamp (or C-clamp). All parts can be removed for easy cleaning and maintenance.

Threaded mounting
The threaded mount allows a user to weld a mount into the processing equipment and then connect the PAT-W using the threaded tip of the spectrometer. This mount also has a removable window to allow for easy cleaning and maintenance. The PAT-W has a built-in 9-axis inertial measurement unit (IMU), which allows accurate and repeatable triggering of spectral acquisition when the PAT-W is mounted on a rotary mixer.
