Application Note: Identification of Organic and Pharmaceutical Powders

Real-time, in-line powder identification usually means a trade-off between speed and accuracy. We proved it doesn't have to. We recently teamed up with our Nynomic Group partner, m-u-t GmbH, to release a joint Application Note. The goal was simple: build a compact, field-ready NIR setup capable of analyzing complex organics directly in the bulk material, […]

Application Note: Measuring Ethanol and Methanol Mixtures with ATR Fiber Probes

Posted on: 
5 February 2026

In the high-stakes environment of complex chemical processing, the ability to distinguish and quantify components like ethanol and methanol in real-time is often the deciding factor between a strictly controlled reaction and an off-spec batch.

Traditionally, operators have relied on manual extraction for laboratory analysis. However, this method introduces significant delays and safety risks that modern industry can no longer afford. When you are reacting to problems identified in a lab report hours later, you are not preventing them—you are merely managing the damage.

The Solution: Mid-IR Spectroscopy with Fiber Optic ATR Probes

How do you achieve laboratory-grade precision directly within the process line, without ever extracting a sample?

One of the most effective solutions lies in Mid-IR spectroscopy, utilizing advanced Fiber Optic ATR (Attenuated Total Reflection) Probes. By leveraging Art Photonics’ proprietary Polycrystalline Infrared (PIR) and Chalcogenide Infrared (CIR) fibers, these probes extend the reach of Mid-Infrared spectroscopy directly into the reaction vessel or flow line.

Key Advantages for Industrial Application

Implementing this technology facilitates a shift from reactive analysis to proactive process control:

  • Remote Sensing: Measurements are performed remotely from the spectrometer. This keeps sensitive (and expensive) analytical equipment safe, even while the probe is immersed in aggressive chemical environments.
  • Sampling-Free Analysis: By measuring directly in the line, you eliminate the need for manual sample extraction. This ensures a continuous, automated data flow and significantly reduces operator exposure to hazardous chemicals.
  • Real-Time Process Control: Operators receive immediate feedback on component concentrations. This allows for instant adjustments to process parameters to maintain product integrity and consistency.

Featured Application: Ethanol & Methanol Analysis

Our latest application note details the performance of these MIR ATR probes in the simultaneous analysis of ethanol and methanol mixtures. The study demonstrates that despite the chemical similarities between these alcohols, Art Photonics’ PIR and CIR probes provide robust, highly accurate differentiation.

The resulting data confirms that this method delivers the precision required for demanding industrial applications, making it a viable replacement for traditional offline chromatography.

Is your process ready for the shift to continuous in-line monitoring?
