Frequently Asked Questions (FAQ) about Process Raman spectroscopy

How does Raman spectroscopy work?

Raman spectroscopy, red and green laser on a black background

Raman analyzers use a laser beam to shine on the sample. The Raman scattered light is then collected and sent to the spectrometer. The spectrometer separates the scattered light into different colors, and the detector detects them to create a raman spectrum.

The Raman spectrum shows how light scatters at different wavelengths. It helps identify substances and study molecular interactions by giving information about molecular vibrations.

What advantages does Raman spectroscopy have for process monitoring?

Raman spectroscopy offers numerous advantages for process monitoring:

  • «Real-time» results: It enables instant insights into molecular changes during processes, providing timely feedback for adjustments
  • Non-destructive analysis: Raman spectroscopy is a non-invasive method that analyzes samples without causing any damage, safeguarding the original state of the monitored substances.
  • Identification of molecular species: It effectively detects impurities, intermediates, or by-products, supporting with quality assurance and control and ensuring product consistency
  • Inline process control: Raman spectroscopy allows for direct monitoring of process parameters, allowing for real-time adjustments to maintain desired production conditions.

What is a Process Raman Analyzer used for?

A Process Raman analyzer is a monitoring system used for real-time analysis of chemical processes. It uses Raman spectroscopy, which uses light to give detailed information about the chemical composition and structure of materials. Various industries utilize these process analyzers to monitor and analyze chemical processes in real-time. Their purpose is to ensure product quality, process efficiency, and compliance with regulations.

In chemical processes, they ensure product quality and process efficiency by tracking reactions. In pharmaceutical manufacturing, they verify drug synthesis processes, detect impurities, and ensure compliance with regulatory standards. Furthermore, they aid in quality control in food and beverage production, polymerization monitoring in polymer production, and pollutant analysis in environmental monitoring efforts.
