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

By Stanislav Perevoschikov

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 […]

How to Measure ATR Spectra Directly in Solution with Fiber Optic Probes

By Stanislav Perevoschikov

Moving Beyond the Bench: In-Line FTIR Monitoring with ATR Probes For decades, Attenuated Total Reflection (ATR) has been a standard technique for FTIR spectroscopy. However, most users are restricted to standard ATR inserts or benchtop accessories. While effective for static lab samples, these setups introduce a critical bottleneck: the sample must be extracted from the […]
