Application note: Precise In-Line Analysis of Alcohol Mixtures with Fiber Optic Probes

What is the real cost of an off-spec batch? In many chemical processes, the precise ratio of components like methanol and ethanol can be the difference between profit and loss. Relying on slow, manual lab sampling means you are often reacting to problems long after they occur, rather than preventing them.

This is where direct, in-line process monitoring becomes essential for maintaining quality and efficiency. But how do you get accurate, real-time data from inside a reactor or pipe, especially in a demanding industrial environment?

The answer lies in robust fiber-optic probes. They act as a direct window into your process, using the power of Near-Infrared (NIR) spectroscopy to provide instant feedback on your product's composition. This technology allows you to:

• Monitor Continuously: Get a live, uninterrupted view of your mixture's composition without ever needing to pull a sample.
• Improve Process Control: Make immediate adjustments to maintain optimal conditions, ensuring consistent product quality from start to finish.
• Increase Safety and Efficiency: Eliminate the need for manual sampling, reducing operator exposure to chemicals and saving valuable time and resources.

Our new application note demonstrates this principle in action. It details how our transflection fiber probe achieves highly accurate, simultaneous determination of ethanol and methanol in an aqueous solution. The results confirm that this method is more than sufficient for the majority of practical industrial applications.

This research highlights the shift from reactive lab analysis to proactive, in-line process control. To explore the full methodology, validation statistics, and results, we invite you to read the complete Application Note.
