Simultaneous Determination of Cu²⁺, Co²⁺ and Ni²⁺ by Fiber-Optic Spectroscopy in the Visible and Near-Infrared Range

The simultaneous quantitative determination of dissolved Cu²⁺, Co²⁺ and Ni²⁺ ions is important in many fields. These include metallurgy, geology, industrial wastewater analysis and the monitoring of biotechnological processes. In many cases, their concentrations need to be measured directly at the sampling site or in-line during an operating process. The Challenge of Metal Ion Monitoring […]

Application Note: Comparing Compact NIR Spectrometers for Polymer Identification

Posted on: 
10 October 2025

How do you ensure rapid and reliable polymer identification in your process?

Near-infrared (NIR) spectroscopy is a powerful, non-destructive technology for quality control, recycling, and in-line monitoring. But with various compact spectrometers on the market, choosing the right one for your specific setup is critical.

Our new application note offers a direct performance comparison, using our Diffuse Reflectance Fiber Probe to analyze six common polymers. We investigated different spectroscopic methods to provide clear, actionable insights.

Key takeaways from our study:

Clear Discrimination: Both Fabry-Pérot and grating-based spectrometers can successfully discriminate between all six polymer classes.

Bulk vs. Granule: We found improved class separation in bulk measurements due to the averaging of scattering effects, a key consideration for in-situ analysis.

Performance Differences: While the Fabry-Pérot based spectrometer provided better class resolution in a simpler model, the grating-based system is often faster and better suited for rapid process control.

This research proves the feasibility of using compact spectrometers with fiber probes for robust polymer analysis.
