Viavi MicroNIR process spectrometer (PAT) for measuring mixtures

Viavi, a pioneer in optical sensors, has another exciting innovation in the field of spectrometry: the new MicroNIR PAT-W process spectrometer. The Micro-NIR PAT-W is a robust, scalable, next-generation system for real-time process monitoring where it concerns measuring mixture homogeneity, Loss on Drying, density, content uniformity and other process analysis technology (PAT) applications. Unlike other NIR spectrometers, MicroNIR does not use moving parts to filter the light, but Viavi's Linear Filter Technology on Foil (LVF). The coating on the foil ensures less shift of the wavelength compared to traditional coatings and offers a deeper suppression of ambient light, allowing for very accurate measurements. This technology is also wear-resistant, because there are no moving parts, and is much cheaper to produce. LVF makes it possible to reduce an analysis device to the size of a golf ball.

Process Analytical Technologies (PAT)

Process Analytical Technologies is a well-known concept in the pharmaceutical and chemical industries, but is less well-known in the food industry. The new MicroNIR PAT-W process spectrometer also includes an orientation sensor which makes the instrument suitable for (rotary) mixing applications, so that it can be determined exactly when a product is sufficiently mixed.

PAT is about design, analysis and control of different steps in the production process, by identifying and monitoring critical process parameters. This can lead to increased process efficiency, reduced production costs and higher quality and safety of the end product. Want to know more?
