Technical Note: Choosing the Right Optical Fiber for Your Process Spectrometer

Is your process spectrometer giving you the full picture? For engineers working in process control and Process Analytical Technology (PAT), the quality and reliability of real-time data are paramount. While the spectrometer itself is the core of the system, its performance often hinges on a component that can be easily overlooked: the optical fiber. The […]

Webinar: Combi Probes - Solving the "Blind Spot" of Single-Mode Spectroscopy

In complex chemical analysis and biomedical diagnostics, relying on a single spectroscopic technique often results in a "blind spot." While Near-Infrared (NIR) offers speed, it frequently lacks specificity. Raman spectroscopy provides a precise molecular fingerprint but often battles fluorescence interference. Mid-IR offers excellent structural detail but is limited by shallow penetration depths. The Challenge: Spatial […]

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.
