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

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

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 […]

Fiber Optic ATR-Probes (Shaft-in-shaft design)

Main features

  • Fiber assembly is easy detachable.
  • No need to retract the whole probe out of the fermenter, just pull the fiber assembly out of the operational shaft and store it separately.
  • Sealing the operational shaft is possible for the sterilization, cleaning, deactivation or any other treatment.
