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.
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.

In modern chemical and biotechnological industries, the ability to accurately monitor process streams in real-time is crucial for optimizing efficiency, ensuring quality, and maintaining safety. Traditional methods like chromatography, while precise, often involve time-consuming sample extraction and offline analysis, creating delays in process control. A more effective solution lies in bringing the analysis directly to the process line.
Our latest application note demonstrates a powerful method for achieving this: using a fiber-optic Attenuated Total Reflection (ATR) probe for in-line Mid-Infrared (Mid-IR) spectroscopy.
The Power of the Molecular Fingerprint
The Mid-Infrared spectral region is often called the "molecular fingerprint" region because it contains unique absorption features corresponding to the fundamental vibrations of molecules. This allows for highly specific identification and quantification. Even molecules with similar structures, such as ethanol and methanol, exhibit distinct spectral signatures in this range, making it possible to differentiate and measure them accurately within a mixture.
Overcoming the Challenge of Liquid Analysis
Directly analyzing liquids, especially aqueous solutions, with traditional infrared spectroscopy can be challenging due to the strong absorption of water. This is where our fiber-optic ATR probe technology provides a significant advantage. The ATR technique allows for measurements to be taken directly within the liquid sample, regardless of its opacity or high absorption. By bringing the analysis directly into the process fluid, it enables continuous, real-time monitoring without the need for sampling or complex sample preparation.
A Case Study: Quantifying Ethanol and Methanol
In our study, we focused on simultaneously quantifying ethanol and methanol in a two-component aqueous solution. By connecting a diamond ATR fiber-optic probe to an FTIR spectrometer, we developed a robust calibration model. The results demonstrated exceptionally high accuracy, with a root mean square error of prediction below 0.15% for both alcohols.
This high level of precision highlights the suitability of the technology for demanding industrial applications, including the control of distillation processes. The use of fiber optics adds another layer of flexibility, allowing the spectrometer to be placed in a safe control room while the robust probe is integrated directly into the production pipeline.
This combination of Mid-IR spectroscopy and fiber-optic ATR probes provides a robust, accurate, and efficient solution for real-time process monitoring. It empowers industries to move beyond delayed, sample-based analysis and embrace continuous, in-line process control.
