UV-Vis & UV-Vis-NIR
Process and Lab Analyzers
Online NIR & UV-Vis Process Analyzers for Real-Time Process Spectroscopy
For four decades, GUIDED WAVE™, a Process Insights brand, that has been at the forefront of near-infrared (NIR) spectroscopy delivering reliable, real-time measurement solutions trusted around the world.
What Is an Online NIR Process Analyzer?
An online NIR process analyzer uses near-infrared spectroscopy to continuously measure chemical and physical properties without removing samples from the production process.
Unlike laboratory testing, online NIR analysis provides:
- Continuous measurements
- Immediate process feedback
- Non-destructive analysis
- Reduced manual sampling
- Improved process control
- Faster production decisions
