Introducing the FlexiSpec Combi Fiber Optic Probes

In the demanding fields of bio-pharma and advanced R&D, real-time data is essential. Traditionally, securing comprehensive analytical data meant physically switching between different spectroscopic setups, such as ATR, NIR, and Raman. This fragmented approach not only slows down critical processes but also introduces a higher risk of sampling errors. Why run three separate analyses when […]

Application Note: Identification of Organic and Pharmaceutical Powders

Real-time, in-line powder identification usually means a trade-off between speed and accuracy. We proved it doesn't have to. We recently teamed up with our Nynomic Group partner, m-u-t GmbH, to release a joint Application Note. The goal was simple: build a compact, field-ready NIR setup capable of analyzing complex organics directly in the bulk material, […]

Application Note: Polymer Classification with NIR Spectroscopy with Fiber-Optic Probes

Posted on: 
25 April 2025

Reliable identification and classification of raw polymer materials are essential for quality control and efficient processing.

Did you know that near-infrared (NIR) spectroscopy combined with advanced fiber-optic probes offers a powerful solution? This technique allows for rapid, non-destructive analysis outside the lab, making it possible to perform measurements right in the field or directly online.

art photonics' Diffuse Reflectance Fiber Optic Probes are designed for remote spectroscopy, collecting data needed for these demanding applications. The data is then processed using Principal Component Analysis (PCA), which enables the classification of various polymer raw materials, even when their spectra overlap.

Our latest application note demonstrates the successful classification of key polymers such as:

• Polyethylene terephthalate (PET)
• Acrylonitrile butadiene styrene (ABS)
• Polypropylene (PP)
• Polycarbonate (PC)
• Linear low-density polyethylene (LLDPE)

This capability makes near-infrared spectroscopy with fiber probes an optimal tool for developing robust Process Analytical Technology (PAT) and automated process control systems in the plastics industry.

To learn more about the methodology and results, please explore our new Application Note.
