Application note: Implementing MicroNIR™ family of sensors for PAT/QbD applications

Posted: 23 December 2016 | | No comments yet

In this application note, Viavi discuss their MicroNIR family of spectrometers that are fully integrated and ultra-compact NIR sensors…

Since the introduction of the Process Analytical Technology (PAT) and Quality by Design (QbD) manufacturing initiatives, Near Infrared (NIR) spectroscopy quickly became the tool of choice for measuring raw and in process material properties due to its versatility and non-destructive nature.

Fifteen years after the onset of PAT, NIR is still the number one choice of most practitioners for applications of raw material inspection, material conformity, blending, granulation, loss on drying, content uniformity and compaction.

Built upon Viavi’s proprietary Linear Variable Filter Technology, the MicroNIR family of spectrometers are fully integrated, ultra-compact NIR sensors. We offer rugged field and industrial stainless steel manufacturing models. The MicroNIR family of NIR spectrometers was designed from the start as a fit-for-purpose sensor to meet the needs of these applications without unnecessary system features and complexity. When these small, robust and process ready sensors are implemented, virtually 100% of materials can be measured and monitored for critical quality attributes and processability, allowing for more efficient manufacturing, resulting in consistent product quality. Because of the unique design of the MicroNIR sensor, several valuable benefits are realised for both field and manufacturing processes.
