MicroNIR PAT-U NIR spectrometer
Continuous manufacturing process control
- compact
- integratable
- real time response
The PAT-U is a near infrared spectrometer used for in-line process control. Used in many industries, it allows real-time monitoring of mixtures, uniformity, drying and moisture monitoring, reaction monitoring, granulation, freeze-drying, and other similar applications.
Advantages
Designed for regulated environments
Designed for rigorously GMP regulated environments, the PAT-U integrates directly into industrial facilities and requires minimal maintenance. There are no moving components or expensive fiber optic cables, resulting in excellent stability and superior performance.
Standard installation
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, 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.
Applications

Monitoring of manufacturing processes (granulation, drying, uniformity, reaction).
Feed & food industry
Control of moisture, protein, fiber, etc.
Industry
