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 […]
